About a week and a half ago, I had my first kiss with a girl (I'm 19 years old and in college). We made out for two hours and I spent the night with her. Prior to this, we had a very deep conversation, and I told her about having aspergers. She was the first person who ever expressed genuine interest in me and my condition. Thing is, she is the RA of my dorm, so it could never develop into anything more than just one night. So, with this overwhelming feeling of being loved and cared about for the first time in my life, I had to let everything go. I expressed a desire to be friends with her, which she has agreed with, but I became fixated on her, and wanted to spend way too much time with her. She said that she felt very uncomfortable with this obsession, so I have limited myself to spending one time a month with her. Yet, I still have these ruminative thoughts about her. I need advice on how to get over this wonderful yet painful experience, and move on.
