She has a boyfriend and I told her how I feel, now what?
So I just came across this site while trying to find advice on how I should proceed and I figured what the hell, I'll just ask. Here's the deal (kind of long):
I met this girl in one of my classes back in January and we really hit it off. We started studying and working on homework together a lot and every time we did, we had a lot of fun doing it. I really don't think I have ever had that much fun doing something as boring as studying. She told me early on that she lives with her boyfriend so I tried to tell myself I shouldn't even try anything with her but I honestly couldn't help myself; she's beautiful, smart, we just click, and we both enjoy each other’s company, a lot. She was always calling me to see if I wanted to study or work on homework and like an idiot I almost always agreed. I tried to keep from falling for her but it really didn't take long until I couldn't stop thinking about her, dreaming about her, etc.
I knew it was a bad idea but I kept studying with her even after I had fallen for her and my attraction to her only grew. The thing is, it didn't seem like a one sided deal, she was definitely falling for me too. She started telling me about how her boyfriend had grown really jealous of me because I was seeing her almost more than he did (she goes to school during the day and he works at night) and even though I was already causing problems for their relationship, she still called and wanted to hang out just as much. As the semester started to come to a close, our study sessions really did just become us hanging out. We'd study or work for a couple of minutes then talk and joke around for a while (people in the library started to hate us).
I was in a bad way for her and I knew I had to do something, the only reason we ever saw each other was because of a mutual class and once that was gone I knew I wouldn't see her nearly as much. I weighed my options and decided I just needed to tell her how I feel even though we both kind of knew how we felt about each other already. So the day before the final, the last day of our studying, I had to tell her how I felt. I'm usually not nervous about much but holy s*** was I nervous, I knew the friendship would be over if told her and things would either get much better or become really bad. I almost didn't say anything but as we were parting ways I stopped her and broke out into my little speech about how I felt and how she makes me feel. She didn't say much beyond "I'm flattered", "I already knew", and "See ya tomorrow" (I still don't know why she said this? We didn't see each other the next day and there was really no way we would have unless she wanted to). As I drove away I noticed she was just sitting in her car crying and I felt terrible.
It’s been a week and I haven't heard from her and I don't really expect to in the future but I still can't get her off my mind. I know I'm probably fairly disillusioned at this point but I can't help but think that there’s still something I can do to make her mine. She the girl of my dreams, I’ve never felt this way before and I can't help but go down swinging.
So... Here is my question:
Is there anything I can still do, is there a chance at all or should I just walk away and look to the future? I really don't know which way to go... (Although I know the way I'd like to go)
P.S. I know I'm a terrible person for going for a girl who lives with her boyfriend so I don't need to hear any of that, just looking for advice folks.
