<human>: Hey, hello! :)

I have a bit of an issue. About a year ago, I left my girlfriend (We will call her Hannah) of the time and began talking with the girl (whom we will call Rebecca) that picked me up off the cutting room floor, and now I am trying to let go of Rebecca.

When I left Hannah over infidelity, Rebecca did her very best to make sure I was okay. She gave me her time, her attention when she had things to do, and she generally made me forget what my ex-girlfriend made me feel like. But she never really took me in. I tried, I flirted as time went on, I pulled all the stops that seemed reasonable, but she never really returned it. It was clear that she wasn't ever going to really take my hand in a relationship, that she was being a friend and helping me out. That is okay, I am not mad at her, I am just a bit stuck.

At the point in which I discovered that she has no intentions of dating me, I tried to find someone else, which I have! This girl, who we will call Alice, and myself are going well, we are even going out for my birthday here shortly. Excellent! I am happy about this, I am extremely content with Alice and how things are going! 

Except for one thing. I feel this extreme guilt. Almost every night I am having dreams about Rebecca. She and I don't really speak anymore, we hardly look at each other, but in my dreams, it is like we are married already. Help! 

I want to let it go. I want to stop having dreams about her, and start finally being free and happy with the woman in my life right now, Alice. I am sick of seeing Rebecca and remembering what I dreamt of, remembering how she would let me hold her hand in my sleep but not when I wanted it.

How do I let it go? How do I stop? Please help :(

<bot>: Got really attached to a girl who didn't like me that way, trying to let her go to be with the girl who does like me that way. Time span 1 year.
