Am I blowing things out of proportion, or are my concerns legit?

I'm 26 weeks pregnant, and I've been married for about a year now. My husband is taking care of the finances right now due to the fact that I am unable to work because of pregnancy complications, but I do have full intentions of returning to work when possible. As you can expect, in our first year of marraige we have nose-dived into many problems, but have managed to work through most. However, just in the past 6 months or so I have noticed my husbands EXCESSIVE use of his xBox, playing some game online with other guys. He's so obsessed with it that we can't even sit down and watch an entire movie without him stopping it to check his messages. When he comes home from work he sits down turns on his xBox and plays it all hours of the night, barely getting enough sleep to return to work the next day. We literally might say three or four words to each other in a period of 12 hours. I gave up on trying to get his attention. I tried dressing up nice and fixing my hair and putting on makeup... it doesn't work. I feel disgusting now and to top it off I'm 6 and a half months pregnant and hating it all. Then to make things even worse, I might come home from a friends house or from being out and I'll get the laptop to check my emails and whatnot, and I find porn sites in our browser history. I have nothing against porn when its the two of us... but i feel even more disgusting that he's finding the time to watch internet porn and not coming to me. I've confronted him several times, and I even told him that if he doesn't love me or isn't attracted to me anymore, that I need to know so I can get things situated before the baby comes. I feel like I'm talking to a brick wall. We're young, and he's even younger than I am, but I don't want to make excuses for his behavior. I love him to death but am thinking that maybe I should be leaving and getting on with my life. I don't want to put myself through this if I don't have to.
