So i have been with my husband for 8years married for 4 and from day one he loves his video games. i never had a problem with it til we had kids. now it seems like xbox comes before everything. its the first thing he does when he comes home from work and there are days we don't see him at all b/c he is playing games. is it normal for me to be jealous of a video game?

Ever sit down next to him, cuddle up, and blow each others' faces off on the X-Box, as a couple?
Could save your marriage.
My suggestion is ask for him to spend x amount of time with you and the kids each night. Play for a half hour or hour when he gets home to unload, then have dinner and enjoy some time with the family. Maybe Saturday mornings he takes the kids out of the house, no xbox, you get a break and the rest of the day you take the kids and he can play xbox or whatever he wants.
Men need this kind of release, whether it's a game, watching tv etc. He does however, need to get in under control instead of letting it control him - he sounds addicted.

Seriously, have you tried telling him how much this bothers you?
Does he have a lot of stress? A lot of guys play just to blow off some steam.
I am a gamer too. But I make time for the wife and kids. Games are very secondary to my family. (My wife would not have it any other way - I can respect that.) I'll usually only game after everyone has gone to bed. A lot of my male co-workers game and do the same thing - game after everyone else is asleep. This certainly makes for some rough mornings though. It ain't so easy to get up for work after 4 hours of sleep anymore.
