V.S.
Are the video games interfering with you and his relationship? It doesn't sound like it is keeping him from doing the things you ask him to do.
At 42, he is a grown man and if it is causing trouble with his work, you let him deal with that. I'd be ecstatic if my husband would do laundry or dishwasher and you're complaining that's all he does. Instead of thinking about all the things he doesn't do, why don't you think of all the good things he does, praise him for it and when you take the kids out to do something physical, ask him to come.
Guys are different then girls- Guys really enjoy playing games that they can conquer. Although we might not understand why, you don't need to nag. He maybe is playing those video games to keep his mind off of everything that keeps him up at night.
Give him a break; it will end as fast as it began. It could be so much worse...
