A/N: As always, thanks for the reviews and I'm so sorry that it's been taking me so long to update.

In a quiet little suburb of New York, Olivia laid down on her bed and started crying. Earlier that day, her mom had driven her, Alex, and Abbie to the airport. They had wanted Serena to join them but Mr. and Mrs. Southerlyn had insisted on driving their daughter to the airport themselves. During the drive over there, they tried to take their mind off of the situation by telling childhood stories and annoying Olivia's mom with their off-key singing along to random hip hop songs. It worked for awhile, but the reality had set in for them before they were even close to the airport. Olivia knew it was going to happen eventually, but she still dreaded the day Abbie would move to Texas. Olivia knew Abbie would have a new life there, maybe even a better life. She imagined Abbie having a stereotypical college life complete with sorority sisters, frat parties, and lots of binge drinking. Or maybe she would have Alex's college life and sip coffee with girls who thought they were better than everyone else. Then she realized that neither of those described what Abbie's life would be like. She knew Abbie was a square peg just like she was. The two of them never really fit in with anyone, which is why they got along so well. The popular girls would recruit them, but they weren't into partying. They were both jocks, but they didn't live and breathe for their sports like other people did. They both got good grades, but they weren't exactly nerds. Abbie and Olivia preferred hanging out with each other and with Alex and they didn't care what anyone else thought. Olivia knew Abbie was going to make friends, but none of them would become her best friend. She kept telling herself that she wasn't going to be replaced, just like she kept telling herself that she wasn't going to replace Abbie. She then thought about how Abbie was going to be living with Serena and sharing a bed with her every night. She'd practically be married. Olivia wanted that with Alex, but she knew it would be years before they could have a place together and that's if they even decided on what state they wanted to live in.

Abbie and Olivia didn't cry when they said goodbye at the airport, but they hugged each other until someone announced the final boarding call for Abbie and Serena's flight. Alex had tried to comfort her, but Olivia refused to let her. Instead, she stared out the window as Abbie's plane took off and she stayed there for nearly 20 minutes afterward. She would have stared out that same window even longer if her mom hadn't led her to the nearby seating area.

"She's gone," Olivia said and finally broke down.

That was hours ago and Olivia still hadn't stopped crying. Her day had been one heartache after another. She had wanted to spend time with Alex, but she knew Alex had a long drive ahead of her and she'd have to leave the moment they got back from the airport.

After seeing what a wreck her daughter was, Olivia's mom offered to spend the rest of the day with her, but Olivia insisted on being alone. She looked at the guest room that had been Abbie's for the past three months and saw that it was just as it had been before Abbie had lived there. Her clothes were gone, her University of Texas memorabilia was gone, and her Chucky doll was no longer sitting on the bed. Olivia knew Abbie would be staying there again during Winter Break, but that was still three and a half months away. She'd no longer get to play video games with Abbie until six in the morning or fall asleep underneath her on the living room couch while watching TV shows they didn't particularly care for.

Before Abbie left, she handed Olivia a folded up piece of paper and told her not to open it until she was alone. "It's like our intimate moment," she said and started laughing. Remembering that line made Olivia start laughing all over again. Even though she had read that letter over 10 times, she decided to take it out of her purse and read it all over again.

Dear Olive,

If you're reading this, that means I'm on a plane to Texas. Unless you're reading it again hours later, which you probably are because you've become sentimental in your old age. Then again, so have I if I'm writing this to you. I wanted to start it out like one of those living wills in which the person says "If you're watching this, that means I'm already dead." I just thought it was funny, but Serena would probably smack me on the arm and tell me I was jinxing myself. Then she would be upset because if I jinxed myself that would mean she'd die too since we're on the same plane. Okay, I obviously have no idea where I'm going with this. All I know is that I'm writing it to you while you and Alex are asleep. You two look so cute, almost annoyingly cute.

I have a mix tape playing in my walkman right now. Yeah, it's mostly Nirvana, of course. This tape reminds me of our senior year. So much happened. I think that's the only way I can sum it up. There were so many good memories though and not just this year but every year since I was in the fourth grade. I realized that almost all of my good memories of growing up are because of you and Alex, but mostly you. I love you so much, Olivia and I'll never stop loving you no matter what happens. You're like a sister to me. A sister that I made out with in the 10th grade. Okay, that's disgusting, but you know what I mean. You and I have the kind of friendship that not many people are lucky enough to have. We understand what the other is saying even when we aren't even speaking. You're the one person I know I can always count on and I know you know you can count on me too. We've been there for each other through so much. You were the first person who talked to me when I still the new girl that everyone made fun of for being southern and having an accent and for being the tallest, skinniest girl in the class. Nine years later and I'm still the tallest, skinniest girl regardless of where we go and I still have that accent. I guess not much has changed. I hope that made you laugh or at least shake your head while reading this. Seriously, though, you were there for me when I found out I was pregnant and when I lost my baby and even when my parents disowned me. I don't know what I would have done without you. I shouldn't be saying that in the past tense. Honestly, I don't know what I'm going to do without you when I'm in Texas. I know I'll have Serena and you'll have Alex, but it's not the same, you know? It's like you were the only person who never judged me. You love me for me and I love you for you.

I don't know where I'm going with this. I really don't. I'm just thinking about everything and I wonder what would have happened if we had made different choices. Like if you would have stayed with Connie and Alex had stayed with Casey. I liked you with Connie. There was a certain innocence about you back then and you were so carefree. You seemed so happy, Livya. Even though there was still drama with Jenny, it was no big deal because Connie, Becky, and Jenny are cheerleaders and messing with another cheerleader's girlfriend is like breaking a cheerleader code or so Connie told me when she was drunk. We both went to football games all the time so you could see Connie cheer and I could watch Trent play. Then I think about if I had said yes when Trent wanted to marry me. Well, he didn't want to marry me but he felt obligated to because of the baby. Then I think about him being at Notre Dame and people watching him play on national TV and then the NFL. He'll probably marry a famous model or actress or someone else ten times prettier than me. I hope he does. I'll be happy for him. Then I think about what would have happened had Serena not stalked me when I worked at the movie theater. I'm really glad because I would have never had the guts to ask her out. Just like I never had the guts to ask you out. I've never told you this but I had the biggest crush on you and when we kissed each other in the tenth grade it was more than just a drunken make out session for me. I was going to ask you to be my girlfriend when we were juniors but Jenny had already beaten me to it just two days before the day I had planned on asking you. I was going to spell the words "Be mine" in gummy bears on top of a strawberry ice cream cake. I think that's one of the reasons I hate Jenny so much. Not only did she have the balls to do what I couldn't, but she had you completely and you even lost your virginity to her. I wouldn't have been upset with you for bleeding on my sheets like she was. You losing your virginity to me would have been the greatest gift I had ever received. But I don't even know why that sticks with me. You were her girlfriend and you were bleeding and scared, how could she have been so upset? I hated her so much, Olivia. So much. She had the one girl I wanted more than anything in the world and she didn't even treat you right. I tried to be happy for you and your "milestones" that you were reaching with her, but I wasn't. And then when she broke up with you, I wanted to swoop in and play the hero, but you were on the rebound and before long you had Connie and I had Serena. Don't get me wrong, Serena is the love of my life, but I still think of what might have been.

The sun is coming up already. I should stop writing this and try to get some sleep. I have a big day ahead of me. I love you.

–Abbie

Olivia still didn't know what to make of the letter, but she was glad that Abbie had been so honest even if it did confuse her. She started thinking about what her life would have been like had she been Abbie's girlfriend instead of Jenny's. Would they still have been together? Would they have remained friends had they broken up? It was all too overwhelming for Olivia.

In a bustling airport in Texas, Abbie held her crying girlfriend as close as she could. She wanted to kiss her, but she knew that was out of the question.

"I miss home," Serena finally managed to say.

"I know, baby," Abbie told her. "So do I. If you want to ever go back, you can tell me. You'll still be my girl."

Serena shook her head. "I'm in it for the long haul. You're stuck with me now."

Abbie couldn't help but smile. "That's the Serena I fell in love with."

"And the Serena you're going to spend the rest of your life with."

Abbie wanted to kiss her girlfriend, but all she was able to do was hug her one more time.

"Abbie!" they heard a woman shout.

"Grandma!" Abbie said excitedly and led Serena over to her.

"Look at you," she said as she hugged her granddaughter. "You've gotten so beautiful. And who is this lovely young woman with you? Is this your Serena?"

"Yup, this is my Serena," Abbie said proudly. She was thrilled when her grandmother hugged Serena and insisted that Serena start calling her "grandma" instead of anything formal.

Abbie's grandfather was in the car and the girls rushed over to greet him after they had grabbed their suitcases. He commented on how much Abbie had grown up and how happy he was that she had found someone to love. Before they went home, they decided to stop at a restaurant and Abbie's grandparents asked questions about how the two of them had met and how Serena knew she was in love with their "little" Abbie.

Abbie had wanted to start unpacking when they had reached her grandparents' house, but Serena insisted on lying down in bed. She ended up falling asleep instantly, but Abbie didn't mind. She held on to her sleeping girlfriend and thought endlessly about what she had planned for their new life in Texas.
