If you don't mind the input of an outsider...
I think that stepping away from gaming for a bit is a very good idea, since your marriage is much more important than any gaming.
You said that you were religious... not to cross the ENWorld boundaries on religious talk, I'd suggest making use of the counselling services they offer. From my own experiences, I'd say that husbands and wives have a duty to each other, and exploring how you can do you duty to your spouse is the place to start. I have never had this exact situation, but I have had my share of bad times. In the worst place I have ever been, I simply said, "I'm sorry, I was wrong, but I love you. Let's get some help and work it out together." You might be surprised how far that sentence can take you, but only if you both follow through on it.
Gaming will still be here in six months or however long it takes you to sort this out! You and your wife will be in my prayers.
