BM, you control whether or not she is in your head or not. Not her. I see a lot of victim mentality in this post. If anything, over the last year and a half, you should have learned that being beta will always get your grapes squashed. Be alpha.
Forget her and her mom for your child-care needs. The less he is around either the better. The courts will say what the minimum is that he has to be around them. Make sure to keep it as close to that minimum as possible.
You need to get to the point where a picture of her with some some slob has no effect on you.
