My current girlfriend has told me about a past relationship she had. She is 22 years old and the man was 35 years old. She had seen him 3 times and they had sex twice. She didn't see it as serious, but just in a sexual nature. She said that she was not even attracted to him, the age difference was akward, but they still engaged in sex. She had only had serious relationships in the past, this was a one time deal, but it bothers me. I feel that she is so special, but she just threw herself at this guy. I can't seem to stop obsessing over it. I play the scenarios over in my head. She was drunk and they hung out while she was housesitting then sex. They went for coffee and then had sex in the parking lot. I am serious about this girl, I think she may be the one. I just don't feel that sex is special with her and the age difference is disturbing (she had never dated anyone older before). What can I do to get over this?
