As I read through your sitch, I can understand why your wife says it is your problem. Everything is great from her perspective. You do everything for her, she gets your attention, even some wine, and all the sex she wants. It just so happens she does want it very much. It is a perfect situation for her, so yeah, at this point it is your problem.
So how are YOU going to change this? How are YOU going to stop serving her so that she no longer has everything she wants? When are you going to stand up for yourself and stop following behind her like a puppy dog? Going to sleep in the den doesn’t sound very assertive. What do you hope to accomplish by this? Do you think she will get the hint that you are upset and suddenly find some compassion within her to sooth your needs?
Nope, don’t see that happening, especially if she has serious issues. Her dysfunction is obvious to you by her focusing on herself, not you. You going off to pout about it is not going to suddenly cause her to notice you. She can’t. She has pushed it down inside her walls where it is safely tucked away and you are helping her to keep it there. Read through some of Corri’s past posts that relate to “rattling the cage.” If you do not want to shake things up so that you can get what you want, then you need to ask yourself what it is that you are afraid of. What keeps you from taking a stand? Then go work on that issue first.
