what would you do?

Hey ladies, so I have a problem. My fiancée is obsessed with the game called world of Warcraft. I don't care that he plays it. But lately it's gotten out of hand. He works 3pm-11:30pm and the first thing he does when he gets home is go on the computer so he can play. He won't do ANYTHING else. Never helps me around the house never helps me with our one year old son, nothing. I do everything. I'm a stay at home mom and full time college student and I still don't complain. I do get angry sometimes when I need a small break and he won't because he's playing his game but eventually he will give me a 5-10 min break. Lately he started following a fb page that's about the game. I saw that he's been commenting on a bunch of girls posts about the game with smiley faces and telling them when he gets off work and his username so they can play together. I told him I don't like that and I don't want him commenting on females post because if it was the other way around he would get mad, so I told him how I felt and he agreed not to do it. Now I just seen that he's doing the same thing again. I don't like it at all, and it makes me feel really uncomfortable. He tried getting me to play the game because he loves it and told me it would be so sexy if I played it. I tried a couple times but I hate it. And ever since he's been commenting on other female girls posts so he can play with them. I don't like it and I told him but he won't stop. What the heck do I do?? Our sex life is awful because we never do it anymore. He goes to work, comes home and immediately goes to play the game. Hours later he comes to bed and falls asleep. I feel abandoned. I don't know what to do.. I would appreciate some advice but please be nice.
