Sorry you are going through this. I read your post and it all sounded so very familiar to me. I went through a bad custody situation and wanted to offer some advice. You need to talk to an attorney asap. Research and find yourself a good one. She cant just take your S away and make her own schedule. My xw tried to do this and I had to get a guardian attorney to get a temporary arrangement while the custody decision was made. Maybe see if there is some kind of program or something to help you w/fees.
Start documenting things in a journal. Start with the behaviors you already wrote about above and keep up on it. The journal I kept was invaluable. Also keep her emails to give to your attorney.
Take care of yourself and keep being there for your kids, they will need you.
