I appreciate all that you've added and I don't disagree. And at the same time, because men tend to have spontaneous sexuality, they can still feel ready for sex even in the midst of all the stuff that has eroded true passion and partnership - but for the most part, women can't. Guys need to understand that. It's not so much that she's rejecting you, it's that her arousal system works differently, and when she's feeling frazzled and unsupported and like you are another one of her children throwing a tantrum, she's unlikely to push you into the coat closet and cover you with kisses. In fact, she's unlikely to look at sex as anything other than a chore under those circumstances. Being mad at her for that is both unfair and entitled.
