I appreciate everyone's feedback. If I was talking to anyone else, I'd continue to ask questions until I was satisfied that I understand the situation. My wife is the only person who resists this and yet she's the person who's opinion I have to consider the most because of the house and kids.
At the core of what I wrote to her was standing up for myself, not saving my marriage. Am I supposed to be standing up for myself or just staying out of her way?
Also, her response to me was fantastic. It was very clear and there is no confusion. That's the kind of communication I'm looking for.
