So, I went out with a guy for 2 and a half years who cheated on me pretty badly (continual thing) and lied about it all, and then about the fact it was more than once for as long as he could. Needless to say we broke up at the start of this year but after a few months tried renewing the friendship we had before we went out.

He got a new girlfriend and I was fine with that - however quite a few times we met up she was (understandably) unhappy about it and when that happened he spent ages moaning about her and telling me how unhappy he was with her but then changing his story and saying but he liked her, but didnt love her even though she told him he loved her.

I know this all sounds very childish for a relationship but bear with me (I put up with a lot with him and I really dont know why)

We met up on monday and he told me they had broken up so after quite a few drinks I kissed him, thinking it was ok as he was single and he kissed me back again after. The next day, courtesy of facebook (of course) I find out they were still together so I told her what had happened, feeling awful because I suddenly became the other person even if just for a minute. I got no reply from her but a call from him asking why I had told her and that he would have (lie)

I then got a message today telling me he still wants to be friends but that I need to back off for a bit - he also deleted me from another social networking site thinking he had put it to private (in places) telling his girlfriend how much he loves her (sounds familiar to me).

I cant help but look online as it is the only way I can get the truth from hiim when he is like this. Clearly he is lying to the pair of us...and to himself and I dont know why I still care because I dont want him back and never could after what he did to me...however he has been an amazing friend these last few months and been there for me at the drop of a hat when my dog and an ex boyfriend of mine died. To back off.... is going to be hard. It took a long time to get over him...I think Im still not fully there and dont know if I will ever be.

Any advice?

I feel sad and pathetic...

I feel like Ive been dragged into his pathetic game he is playing and I know I should get out but its so hard.
