stbxah did the same to our kids and that was the day life became crystal clear to me. Once I decided I would no longer take his abuse he needed a new target. That is when I read the post on how to leave and started to make my plan. I was so thankful for that post because I was overwhelmed. It helped me focus on what was important. There was no way I was going to let him start his garbage with our sons.
I am happy to read your post. Be safe--it is scary when you leave--predictable or not, some times I would try to convince myself that he would not hurt me or the kids. I am happy I did not stick around to find out.
