Long back story summarized in a couple sentences: She was one of my best friends in college, completely friendzoned, but I was really into her. She knew it, but I had to tell her before we graduated anyway. She turned me down, which I knew she was going to do, because she was into some other guy. We graduate, 2+ years go by without much contact. She recently broke up with her boyfriend (the guy she turned me down for) and we hung out for the first time in a long time over the weekend, along with a couple mutual friends. So, here's the issue. Sorry, I know it's long, but fuck it, read it or don't, I don't really care. The main topic of discussion between the two of us that night was about us potentially getting together. She seemed very confident that we had a future together, saying stuff like "we're perfect for each other" and talking about how it was good we never went out in college because it wouldn't have lasted. She was very affectionate and touchy-feely, and we stayed up all night, talking about various things. We wound up falling asleep when the sun started to come up because I was tired as hell. Yes, there was a lot of alcohol involved, but it was similar the next day when we were both sober. I didn't make a move, although maybe I should have, but whatever, we talked about how neither of us would want a one night stand. There was never any real closure to the conversations, it was just a lot of open-ended stuff. My main problem is, how am I supposed to go into that without feeling like the backup plan? 2 1/2 years ago this was exactly what I wanted. But she turned me down for this guy, went out with him for over 2 years, and now comes to me when she realized she was wasting her time with him. We hardly talked the whole time she was with him (he didn't let her see me at all), and at one point I was somewhat sure I wouldn't hear from her again. What would OT do in this position? If we did wind up getting together, I'm pretty sure it would last. She's one of the few people I've ever felt a real connection with, but I'm having trouble with this whole Plan B feeling, you know? I'm mostly just venting, but any advice or comments from people with similar experiences would be cool.
