I am tired of the games

I have been seriously thinking about filing for a divorce from my husband of 2 yrs. The guy has become very unaffectionate towards me because all he does is play his computer game all day. It is so bad that we have not slept together in a while because he comes to bed at 6am in the mornings because he's up all night playing his game. I'm sick and tired of it because he's not romantic anymore, he doesn't do spontaneous things like surprise me, and he doesn't come up with different ideas of things that we could do. All he want to do is sit in the house and whenever we gets invited out with friends, he whines like a little kid because getting him off of his game is like pulling teeth. I need your honest opinions on what I should do because I'm fed up.
