"I can't do this with you anymore, Demi!" This is killing me! I try and I try and I just can't…" Selena's voice trailed off, leaving a hollow echo to bounce off the walls until it faded into nothing.

The two girls had been screaming at each other for the past twenty minutes, arguing about what Selena had just walked into that morning.

She had called Demi the night before, knowing she had gone to a party after a bad day. She called three times without luck. Praying for the best because her mom would never let her go check on Demi so late at night, Selena went to bed early.

Selena woke up around seven o'clock and immediately thought of Demi. She gave no thought to her appearance and simply slipped on her shoes and grabbed her keys. Calling Demi on the way there and still getting no answer, Selena began to worry.

When she arrived at Demi's, Selena saw that her car was parked in the driveway and breathed a sigh of relief. Her parents were out of town once again, so Selena decided to go inside, just in case. She let herself in with the key that was hidden in the garage and made her way to her best friend's room. When she walked in, her voice caught in her throat.

Demi laid in her bed, completely naked, a stranger lying face down next to her, equally without clothes. There were plastic cups on her nightstand, half full of a liquid that had a bitter odor which filled the entire room.

"How could you?" Selena questioned loudly, making Demi jump and nearly fall off the bed. The stranger next to her woke up and scrambled to put his clothes on, thinking Selena was in a position of authority to Demi. He ran out without a word, leaving Demi to defend herself alone. She stood up uncertainly, obviously still quite tipsy from the night before.

"Selena," Demi chuckled. "It's not what it looks like." Demi tried to make it look like she didn't care, but in all honesty, she was trying to fix things before they fell apart. But fall apart, they did. And now, here they were, tears streaming down Selena's face. Demi stood weakly in front of Selena, wearing nothing but a blanket and a smirk, as if it were all a sick joke. She was still drunk and not entirely grasping the seriousness of the situation. But even when Demi was sober, Selena didn't recognize her anymore. Demi was cruel, almost evil to Selena. She knew her weaknesses and used them to tear Selena down, piece by piece. Demi was the reason why she cried herself to sleep nightly. It was easier to lie to Selena than to herself. She told Selena that everything was her fault; that she didn't love her and she never had. But still, if Selena said goodbye, Demi would beg for her to come back and apologize for the things she said. Of course, Selena always forgave her.

This time, things had gone too far and Demi showed no remorse. In fact, Demi's smirk suggested the complete opposite. Selena swore her pain brought Demi absolute joy at this point.

"It's killing you? Oh please, you love this," Demi taunted Selena, picking up a cup from her nightstand and taking a drink. "You love the fact that I've fucked half the neighborhood. It just makes our alone time even hotter." Selena felt sick to her stomach. She didn't know this Demi, not at all.

"Demi, stop."

"Come on, Sel. Let's do it right here," Demi laughed mockingly, putting her hands on Selena's sides.

"Demi-" Selena was cut off by Demi's insistent kiss, rough and emotionless. Her breath was foul with the smell of alcohol. Selena pushed off of her and slapped her across the cheek. Demi regained her smirk in reaction.

"Who are you? This is not the Demi I know, this is not the girl I fell in love with. This isn't you! The old Demi; the real Demi would never act like this! Do you realize what you've become?" Selena was bawling and Demi's smirk was gone. "You are exactly what you said you'd never be. You've forgotten about me. And it hurts, Demi. I can't do this anymore. I wish I could, but I can't. I'm sorry, Dems. I still love you and I always will, but this is it. I'm so sorry. Take care of yourself, Demi." Selena took a deep breath, turned and walked away. Demi just stood there, watching. Speechless. Helpless.
