man trouble... again :(

It all started about a yr ago when I met this guy online,who lives in anoyher country, I was at the time dating someone else, but the guy online was just a friend for 6 months, so no I wasnt cheating. I did in the end sort of break up with my boyfriend for him, although it was time for that relationship to end anyways. The problem came when I was single and I asked this guy I met on the net to come see me… he kept making excuses etc for 2 months and I thought there must be somthing wrong with me. We had from early on knowing each other swapped photos and stuff. Anyways after waiting for so long I finally said that I was just going to have to stop this if he didnt tell me why he didnt want to come see me… turns out all those photos were not exactly acurate. in other words he lied and sent me photos from like 5 years ago, and now he is very overweight. Now I am not a really shallow person, but I think we can all agree we have a certain type of man we like, and im sorry but I am really fit and active and I dont find fat attractive. But because I liked this guy so much and would have felt terrible for stopping things cause of weight issues I kept up with the online relationship. He has come to see me twice… and I really have tried to get over the weight thing… but now I just cant handle it anymore. He’s so sweet and trying to loose weight, but he wants to take our relationship further physically and I really cant handle that. Also the fact that he lied to begin with makes me kinda mad still… I feel like I was cheated into this in a ways cause I fell in love with him thinking he looked completly different. So I dont know what to do… I used to talk to him everday, but now im afraid hes going to pick up on what im feeling and I hate hurting people. any help you can give would be great, thanks x
