Hi Lazy. I hope I can be of some help.

I can relate to a decent extent to your boyfriend. While I don't let it interfere with my social life, I've seen the sun rise over a controller once or twice. I don't think that's entirely abnormal, but if he has a child, it's time for a priority shift, in my opinion. It is, however, pretty easy to get "absorbed" into these sorts of things. There is certainly a subculture among gamers, and some even consider "gamer" as a title to describe their lifestyle. Not bad per se, but if it interferes with a relationship or a child's well being, it's time to put down the controller.

I've known people who speak in the same manner you describe, and it is hard to feel comfortable talking to them or in their presence. If I were you, for both points, I would sit him down and tell him precisely how you feel. It is possible to be honest and get your point across without being "pushy" or impolite.

That's my input, at any rate. I hope I was of some help.
