man your story is just like mine, she would give me sex too but the last 2 months it has felt like rape for me and her.
i too believe my wife is not looking for that in a relationship, she wants just to feel loved and wanted for who she is. whats sad is she is only 34 and after a couple of kids has wieght issues which i never said a word about. as well as some depression problems.

before we were married she was a social fiend, she loved just being around everyone as much as possible.
we got married and that changed, not because i said nomore she just never wanted it again until recently.
after 12 years of marriage she wants to be able to go anywhere she wants for as longs as she wants and nevermind me and the kids.

i pray you and i both beat the odds that are against us, but like you i am discouraged by what i read here.+

be strong and work on your own issues, we can can only change ourselves.
