Much needed advice seeking!

I am looking for some advice on how to get out of the roommate phase with my husband. We have been together 21 years, married 7 years, and have a 16-year-old son together. We do not talk about much anymore. Lots of damage has been done to our relationship (Cheating, lies... those kinds of things... but that is another story.

So, I had to have a full hysterectomy in 2018. I was 38 years old.

Since then, I have no desire to have sex with him or anyone, and now that I am 46 years old, I am really not interested in being with anyone, to be honest.

Him and I can not seem to have talks about feelings or money without a WAR starting, so we just avoid it. That's his only dealing method- is avoidance. We have never shared a bank account. I am the breadwinner for the family and have helped him get every single job he's had in his adult life.

I am so lonely most days, just to have someone to just ask how my day was and actually care what my answer is.

Is there any hope??
