Sexless marriage

We haven’t had sex in over a month, and before that it was pretty sporadic and forced. I’m not sexually attracted to him anymore because he’s literally become a man-child since we’ve lived together. And this isn’t something I could’ve foreseen before getting married. He actually put in effort before. It’s just been a slow unveiling from my eyes to finally see how it’s been effecting me mentally and physically.

It’s burnt me out to the point where I don’t even want to orgasm on my own. I physically can’t. Like my body has completely shut down to the point where I can’t find any pleasure. Yet I really do want satisfying sex. Just not from this situation where I work and then come home to someone who doesn’t consider me or see anything as their own responsibility.

Has anyone gone through this?
