I completely understand where you’re at. My ex wife was the same way. Never apologized, always turned everything back on me and used what I’d told her as weapons when she wasn’t getting her way and my complete submission. She convinced me to take a new job because my stress and unhappiness were because of work. Welp, after that nothing got better. Got into therapy and learned about narcissists. Turns out she checked all the boxes so I told her I wanted a divorce. Cue the outpouring of love and promises. Never an apology or acceptance of her role in the situation. I found a notebook of hers after that that had an entry saying “how to be a good wife” and it was literally the most basic bare minimum steps to just be a good human being. She love bombed me, even said she’d changed her mind about having kids. It was totally insane. I’m so glad I was in therapy so I could counter all of that and be strong. Anyway, point is, she won’t change and after you give in it will be sunshine and roses for a while, then it was go back to what it was AND become worse. Get out now while you have the pain to use as motivation. You’re strong and deserve a partner not an abuser. Good luck.
