I've been in a situation like this in the past. I met a guy online that I thought I really liked and I really thought he had a genuine interest in me as well. He was one of the first men to tell me that I was beautiful, so naturally I fell for him (the idea of him, more likely) we had a lot in common and had fun conversations. He was significantly older than me, but he never took advantage of me or anything like that... but the age was definitely an issue for him. When I suggested that we meet and date he pulled away. Eventually I had to realize that he was using me as a girlfriend substitute and by keeping me at a distance through online contact he knew that I would always be there as a back up (or as someone to always make him feel good about himself) so I eventually had to face the facts and admit to myself that he really didn't want me. I feel like this was long winded and I apologize... but I hope it helped.
