I agree with Steve about the child support. I have full custody of my kids and chose to receive no child support because it was something that would keep my tied to her. The less I have to deal with her, the better. Is it hard? Yes, but I make it work because in the long run, it's what is best for me and my kids...
If she's as toxic as you say, keep moving on and don't look back. Don't worry about the pictures or who she is with. The hard part is over. Now it's all about building the best life possible for blakmac and son...
