Emotionally battered

I have a husband we have been together for 13 years. We have 3 kids.

I caught him multiple times cheating through chat over the past years but the most recent was in 2022 when i realized that the burden was heavy for awhile.

He used to be sentimental. I am sentimental. We never forget monthsary, anniversary dates etc. Fast forward, he doesn't seem to be this man anymore. When he does something wrong he expects me to just Forgive him no questions asked.

He doesnt communicate, he doesnt listen. On the other hand, I am dying to tell him that I am barely hanging a thread.

I am slowly getting used to just keeping quiet. But it is slowly eating me. I have trust issues, I doubt and overthink. I dont know what to do.
