Hey, I think there are great health benefits to being a vegetarian and that there are other moral reasons to be a vegetarian. I am not currently a vegetarian. So?
You write: "For example, the article states, "The best sex is the mutual giving of our body to our spouse -- nobody should be making anyone have sex; that's selfish and using the other person for your personal gratification and purpose." Yet he's insisting on sex when he knows I don't want to."
This I take it is where you say his actions contradict his beliefs. Well, maybe not. The article says the "best" sex is mutual. Certainly he could agree to that and want more of it even if he is willing to tolerate one-sided sex to meet his physical needs. Indeed, maybe he is trying to encourage you to be a more engaged sexual partner. The one-sided sex isn't going to be great for him either, ya know? It probably hurts him and makes him feel unattractive and unloved.
As for the rest, if you actually believe your H makes you have sex when you don't want to, you might want to consider filing rape charges. If what you are saying is that he pursues sex even though you lack interest, and then you choose to have sex even though you don't want it, well, you kind of need to own your choices.
I suggest you take him at his word. He seemed excited when he thought you heard him. H wants more great mutually satisfying sex. How can you engage more sincerely in sex? How can you enjoy sex more? How can you demonstrate in an authentic way that you want physical intimacy with H?
Why do you keep trying to trap H, trip him up, find fault, blame? Why do you keep trying to teach him a lesson? No one wants a cross mother as a lover or romantic partner.
