I'm terrified of losing him ,Will he stay mad at me.. Is my relationship ruined :(?

Ok so this guy I'm friends with online (ps3) added me on Facebook. He lives in a different country and I don't even talk to him or know him in person just online.. I accepted his request and he was been a little weird leaving xxx after messages and my boyfriend was not happy.. So I removed him and told my bf i had him removed and not to worry about it..but I'm still friends with him online.(ps3) that's ok. A few weeks later He requested me again and said he would not be strange or leave comments on every one of my posts or include xxxxx.. I thought fair enough once he was not bothering me on it so I went ahead and accepted him again. He commented on a post and my bf had not known I accepted him as a friend again as it was late at night when he requested me again. He text me the next morning after seein the post from him saying that I lied to him about removing him so I text him back saying that I had him removed the first time I said he was gone but told my bf that he requested again and wAsnt been weird so I accepted.. He is really pissed off with me now for doing that and asked me what else I doing that he does not know about.. I told him to calm down because I removed him again and apologised saying I did not mean any harm by accepting him and never knew it would bother him :( I admitted to been wrong in accepting him again and said sorry but he is pissed now.. He thinks I lied to him in a way I think I probably did and I feel awfull I don't want him to be pissed I just want to forget It ever happened and move on.. What should I do?? :( I'm so upset right now.
