Can we possibly be friends again after intimacy?

[Chris]

I met this girl right before the summer and though I really liked her we were just friends because she said thats what she wanted. Then about a month later she ends up telling me she really likes me but we can't be together because at the end of the summer she had to start med school which was two hours away and she couldn't afford to mess it up with distractions like a relationship. As I start telling her I'm fine with this she kisses me and we end up making out. For the next few weeks things definitely went beyond just friendship. We were going out weekly, talking all the time and things got more heated physically. As her move date got closer though she suddenly pulled back saying we needed to be just friends without any complications like being physical. When I told her I was really hurt and felt used she explained that she never meant to hurt me and that she had liked me but the timing was awful and we were better as friends. Thus we agreed to be friends. I really would like to be friends with her because she is an amazing girl and we grew really close over the summer. I also know though that we crossed a line we can't uncross and I don't know if I can ever truly view her the same way again, especially since I still have feelings for her. I really don't know what to do. Can we go back to being just friends again after the intimacy we had?
