Do you know, it was one morning I had run around getting DC ready whilst ex had behaved like lord of the manor, and then basically said it was my fault we would be late and walked out the door with DC without me.
When he came back, having dropped off DC, I told him to leave. He has never since then been back over my threshold.
It was the straw that broke the camel’s back. There had been a reason I wanted to take DC that morning and had been looking forward to it.
The whole relationship was characterised by him being controlling and emotionally abusive but I did not really see it at that point. I just knew my anxiety could not take it any more and he needed to go. He left me at home like I did not matter, and there was no reason to do that.
Funnily enough, I don’t suffer from anxiety any more.
Please do not beat yourself up about what happened today. You did not cause the situation. You responded to someone treating you quite nastily (very nastily). I do think he crossed a line by treating you as a child and saying what he did about you. The thinking about leaving him comment is spot on, although he should be the one to leave not you.
