Whats the deal here? Have I doomed my relationship or can these things work out? Is there anything I can do to get her back?
Well, as has already been said, this is something you need to let her do. Unfortunately, you probably can't do anything to change her mind; you tried spending time with her and that didn't work, so she seems pretty set in her ways. However, given her distant manner, I'd say she spent a while thinking about it. She definitely cares deeply.
As I said, though, you've got to let her do her own thing. As good as a relationship is, sometimes there are things that need to be done which you can't change. If you want to win her back, don't mess around with any other girls. Stay true to her and show her that you'll always care for her. Don't talk to her less or anything; try to maintain contact and stay close.
If all goes well, she'll come back to you. If it doesn't, I'm not sure there's much you can do...
You sound a lot like me, though. This is creepy.
