If your son continues to live w/you, then you don't pay child support. She's going to be angry about that, but you need to put it in writing to stipulate that if he lives w/you, then you provide no child support to her. In fact, it might be the exact opposite and she may end up paying you.
I'm sorry that this is happening, but no one knows what the future holds, but it sounds like she's made up her mind and wants to cut the ties w/you. Maybe once the ink is dried on the decree, she can finally start dealing w/her issues.
Please take care of yourself and your son.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
