Of course, Walking is feeling dejected, and especially burdened since he's picking up the slack around the house. He wants to get therapy, do something to help the relationship -- but his wife's just saying that he needs to love it or leave it.
It's always a little frustrating as a WoW player to read about this kind of thing. My personal stance is that if they're having this kind of problem from World of Warcraft, the same would have cropped up with something else eventually. Issues like these don't appear magically on their own, wrecking houses as the login screens comes up.
Amy does direct Walking to Online Gamers Anonymous. As she points out, they've got a 12 step program and everything. Well, good luck to them. I really do hope they manage to get the problem worked out. Quitting WoW can be done, but they'll need more to solve their family issues.
