I think you described our M to a tee. I didnt see what was happening then, and either did W. Lack of communication. I see it now, and I hope she will too someday.
Ive thought alot about it, and with me I need to have the problem (any problem) solved, to be intimate. W wanted to be intimate to solve the problem. We were just fighting each other and didnt know it. Hopefully this can be talked through and understood in C.
