All right, well, we had the discussion last night... sort of. He came in, immediately powered up the X-Box, and I said, "You're going to play video games?" in this weird tone that even I was thinking, "Whoah... serious." So he says, "Do you want me to turn it off?", and I nodded my head, and he turned it off. I asked him to please fold the laundry in the dryer, but before that, I told him that we've already had this conversation about him playing video games and not helping me out around the house, and I'm really sick and tired of it. He just starts going, "Okay, okay....", and said that it wasn't okay, that he needs to knock this crap off. He went down and didn't just fold the laundry, but started a new load and did it correctly. Then, I was washing the dishes, and stepped away to let one soak, and when I came back, he already had it cleaned and had moved on to the others.
Have you told him that you MISS him? That you are lonely when he goes off gaming?
Because one thing I'm seeing--the only thing he got when he turned off the games was a scolding, and chores.
Not much of a reward.
Tomorrow, ask him to turn off the game, and then ask him to go for a walk with you. Ask him to read the newspaper to you. SOMETHING.
Also--make chores more fun. You're trapped in the house while you do them. Make that a positive. Treat it as something you can do together.
Seriously--working together on something breeds intimacy. That creates closeness. It's crucially important to a marriage, actually.
Make a rule: Nobody does dishes alone. Nobody does laundry alone (if space is squeezes by the laundry machines, you have to do it with one arm around one another).
Nobody dusts while someone else is reading, gaming, whatever. At the VERY least, whoever is doing chores should be accompanied by someone who is doing some other chore (in toddler-dom, we call that parallel play, and it is very important and emotionally rewarding at times).
Or, if you're washing dishes, then he can lean on the cabinetry and read you the funnies, or talk to you about your day, or plan with you what you'd do if you won the lottery, or fantasize about European vacations, or something.
NO ONE--not you, not him--is alone while they are doing chores. They have company. Hopefully helpful company (so the chore becomes a "joint activity"), but friendly and engaged company nonetheless.
