The fact that I go to church is suddenly a big deal to her. She's not an atheist, but doesn't have much use for organized religion. That's her choice, I don't have a problem with that. I just told her that while I'm 100% committed to working on my shortcomings as a husband and as a man, a spiritual life that happens to involve church isn't one of them. I told her I refuse to be someone I'm not just to please her. You'd think that would be comforting to her; that I'm not willing to lie to her to get her to stay. It didn't work that way. She used is as ammunition against me; "proof" that we're not compatible.
The next time W brings this sort of thing up, I'd say:
"I can see why you would think that. To me, I think it's important that we BOTH have separate interests and common interests. That is the foundation in a healthy marriage. I am comfortable with going to Church because I enjoy it. You don't have to agree with it and that's okay with me."
