....never enough

He said he has noticed that I have been distant lately..as in not wanting to have sex. I am tired of explaining that I am feeling triggered especially when I have to give in to sex just so he will stop whining. He said he wanted a divorce because I am not being a "good wife". I am glad it was he who brought it up, but now I am scared of how the divorce proposal will affect the kids. The kids just became stable in school, finding friends, and maintaining a routine. I can't afford this place on my own. What am I going to do?...all because I wont have sex.
