Girl, I hear you on that. My husband is in the military and is forever playing Call of Duty. He ignores me when he's on it too. I'm 4 months 1 week pregnant with our first child, and I'm tired all the time and just want to spend time with him when he is home, or would like help around the house, since he never cleans up after himself either. It gets lonely being an army wife with their long hours, and with us ladies being pregnant and hormonal on top of it, **** gets rough. I don't really know what to do. I will tell him about it or just straight up *****, and he gets mad as hell. I too am scared that he is gonna be the exact same way when the baby is born.. I definitely don't think you're over reacting though.. Just try to be blunt, or cut him off in the sex deparment so he knows what it feels like. That's what I was suggested to do.
My hubby too is an avid gamer and does not like to watch TV. When our first son was born he showed me that his son was more important than any video game. However I too sometimes feel as though I'm ignored when he plays especially when I try talking to him. I make sure I let him know exactly how he makes me feel. Then he tries harder. He will more than likely always play games that is part of who he is u can't ask him to change that. But you.can ask him to spend more time with you. My hubby isn't one that takes 'hints' I have to straight out say what I want. Good luck hun!
