A couple of months ago I met a great guy online. We dated for a couple of months until January when he told me he didn't feel a "spark" anymore and if someone came around he would go for her. I understood that even though I was madly in love with him and had given him my virginity. We decided to remain friends because even though he didn't feel that spark as a couple but he claimed to still have felt it as a friend, so we became FWB because after all we have needs. A couple of days later he met a girl on a dating site and started talking to her and go on dates. Last Monday he told he was going to date her but didn't want me out of his life. I told him that our FWB arraignment was over and that I wasn't sure I still wanted to be part of his life. The thing is that before he decided to date her we had agreed that I would be living with him for 2 weeks until my new apt was ready (my lease expired so I had to move out). I should mention that since I agreed to remain friends with while he dates the other girl I have tried my best to be very supportive and give him neutral advice on their relationship even though I'm heartbroken. I've learned that he is very frustrated because even though they have technically been dating since early January they haven't even kissed let alone had any type of body contact (no holding hands, no hug, nothing). After telling me he wanted her instead he decided to tell the other girl about me since I was going to be living with him for the next 2 weeks. They went on another date on sat and still nothing, which only frustrated him even more because he assumed that after telling her everything about me and telling her he didn't want to be with me they would have at least kissed. Yesterday was my second day there and everything was fine until the night. I got home cooked, exercised and bathed, then he came and we had dinner. I cooked pasta so we had wine with dinner and after sat on the couch to watch some TV. Problem is that while I was on the couch we were cuddling (I know, first mistake) and his arm was around me. He started touching my back and worked his way down to my thong. That turned me on and of course I didn't want to stop him so I unzipped his fly and grabbed his penis. Apparently this turned him on so much that the next second he took me, slammed me against the couch and we made out. We were very close to sex when all of a sudden he stopped, then we once again continued until I started taking his shirt of and he stopped me. I got really pissed after that and went into his bedroom (I had been sleeping in the living room) and masturbated. After that he wouldnt look at me so I went out for a walk and by he time I got home he was asleep. This morning I was out of the apt before he woke up so I haven't spoken to him yet. My question are: Did he cheat on the other girl with me last night? What should I tell him today? Should I ignore him? Also, shouldn't the fact that he initiated everything mean that he doesn't feel as strong for her as he thinks or is it just him being sexually frustrated? I need some desperate advice ladies.....
