"They give husbands reasons to ignore their wives and freaking ruin relationships. grrrr
Can you tell my husbands a gamer? I haate it!"
Kara, ugh... I know just how you feel.
My boyfriend of four years is an xbox addict. He will deny it all day but there's no other word for it.
When we first met, he didn't have a console. Heck, he didn't even have a TV until we started dating and I brought mine from my parents house so we could hang out in his room and watch movies and snuggle. We used to go out all the time.. We'd take walks in the park, on the beach, go thrift store shopping, have nice dinner dates. And he used to cook for me all the time.
Then right before Halo 3 came out, he bought an xbox 360 with his tax return and I swear, there hasn't been a single day he hasn't at least signed on Live to check it out, except for when the xbox crashed and we didn't have it for two weeks. Right now he works like 6 hours a week and gets unemployment from his last job, and he'll wake up in the afternoon and then plays Halo, Mercenaries 2, Battlefield: Big Company, whatever until like 6am. And what's worse is he plays with his friends from Iowa on there instead of going out and making new friends here in Florida, so it just makes him that much more homesick.
We're currently going through a really rough patch as well, his suitcases are packed in the living room and he was going to move back to Iowa today but I think we're going to try to work things out. But I honestly think if he didn't get his xbox things wouldn't be this bad.
And for the record, I've tried playing with him but he hates playing split screen and complains the whole time, plus I kind of suck so he doesn't want me messing up his game 
I hope you can get things worked out or reach some sort of compromise. Just wanted to say you're not alone.
