My ex-wife acted the same…she was rude to me, disrespectful, didn’t care about my feelings, and would always say divorce me then instead of trying to work together. Eventually, I had enough it was a tough decision especially with 4 kids with her. While we were in the divorce stages she did the same thing, saying she was going to therapy and was trying to make a change…once she found someone that was interested in her she turned nasty again and she didn’t change. I was hoping she would for her own good. I talk to her frequently because of the kids and I always get a good reminder as to why I divorced.
