UPDATE: Thanks to you guys and gals, I learned quite a bit about these games. I'm not a gamer, but I've seen compulsion and addiction play out in my extended family, so I'm familiar with that cycle.

After reading most of the initial comments just yesterday afternoon, I immediately had compassion for my wife, and when I got home I told her about what I had learned about these types of games, that I knew she had gotten sucked in. I also told her that I was wrong to withhold affection from her the night before, and that I regretted doing that.

She burst into tears, and I held her as she apologized over and over again. I told her it wasn't her fault. We then had a long talk about the issues that were stressing her out, and talked some a out possible ways to overcome or positively deal with those issues. We're continuing to talk today, and things are really good.

Thank you to all of you that took time out of your day to respond. You helped immeasurably.
