<human>: A little background, A girl that I met through mutual friends and I started to get romantically involved. Lots of snuggling, Netflix, dates, kissing, etc throughout the course of a few weeks. Now being young this has been the first time that I've actually had feelings for a girl rather than seeing her as another potential sex partner. We had another date and then out of no where during a movie she said she didn't want a relationship at the moment. This rattled me, but I can't force her to change her mind. But the next week she is dating another guy, which absolutely devastated me. Worst part is he looks exactly like me and that has left me with the constant thought of what I did wrong. Its been about a month since those events but I still can't get her off of my mind and its really bumming me out. She is also in my current friend group which makes going out with friends a painful experience. What should I do?

Can you summarize the given text in a few sentences?
<bot>: Girl I liked dropped me like I was hot, then turned around dating another guy. Can't stop thinking about her. Any advice to cope?
