I could have written the exact same words . I'm being treated exactly the same way. My wife gave up on our relationship long ago. No intimacy , no love , period. Places all the blame on me.
Gaslighting me excessively. Everything you wrote. Like you , I'm ready to give up on the marriage of over 30 years. I don't know how old you are , hopefully your young and can start a new life.
I'm older and feel the window is closing on me. I just don't want to go unloved . I gave so much. But all she does is take.
I'll let it go for now. Good luck to you.
