"Mom!" Regina hurried to the foyer as she heard her son's worried voice.

"What's wrong, Henry?" Her voice was laced with just as much concern.

"I saw Ma running out of the station crying! What's wrong with her?" His worry was still evident in his voice.

Regina frowned. "Emma? Crying? You sure it was her?" The boy nodded.

Hastily Regina pulled out her phoned and called her Blonde girlfriend.

"Hi, you've reached Sherriff Emma Swan. I can't answer the phone right now, but leave a message and I'll call you back! *BIEP! *"

"Emma, darling, could you please call me back? Henry saw you leave the station crying. We're worried about you, my love." Regina said before ending the call.

"Voicemail…" She informed her son shortly.

The Brunette mother led her son towards the living room and made him pick a movie in order to distract him from his other mother.

It didn't work. Less then halfway through the movie Henry kept looking at the front door every few seconds, hoping his other mother would come home.

It never happened. Regina tried Emma's phone again, but again without success.

That night Regina agreed to let Henry sleep in their room, at least until Emma came home.

As the sun came up, neither mother nor son had slept one second. Emma hadn't come home that night.

Regina decided it was time to call her girlfriend's usual hangout's to see if anyone had seen her.

First came the Sherriff station, 'cause that was the last place they had seen her, but David told them she left early the previous day and never came back.

Then she called Ruby. Everybody knew that the waitress had become Emma's best friend. If she didn't know where Emma was, Ruby was usually the one to call, but apparently not this time.

"Emma came to the diner yesterday. She seemed upset, but when I tried to ask her what happened, she grabbed her coat and ran out. I've tried calling her a few times, but she doesn't pick up!"

Regina thanked her and told her she'd let her know if she heard from her and vice versa.

Next up was Snow. Although she didn't want to hear the annoying woman's voice, she was desperate to find Emma.

The phoned was answered with a few sobs. "Snow?" Regina asked, hoping the sobbing didn't have anything to do with the missing blonde.

"She's gone, Regina! She left you a note here, but she's gone." She disconnected the phone, grabbed her keys and drove herself and Henry to the Charming's apartment.

Still sobbing uncontrollably Snow handed Regina a folded piece of paper. She opened it and written on it she found two words, written in Emma's signature handwriting: 'I'm sorry!'

When the two of them came home, they found Emma's keys on their usual spot, but everything else that belonged to the blonde was gone.

This time Regina found a note on her and Emma's bed. It read:

My beautiful Regina,

I can't stay! I'm sorry I had to trick you into leaving, but I couldn't face you.

I'm sorry for leaving, but I feel like I failed you in a way I could never tell you! Please, do not blame yourself, it's 100% my fault.

As hard as it will be for you to understand, I really do love you and that's the reason that I left. I'm sorry for not saying goodbye, but if I did it would have been impossible to leave you.

Please tell Henry that I love him and that once I find a way to understand how all this happened I'll contact you both!

I hope that once that'll happen, you'll be able to forgive me?

Love always,

Your Emma

Ps: Henry, please take good care of your Mom for me?

Regina's heart broke. She cried and cried for days.
