Sometimes it is hard to see the forest through the trees. You wrote," I have spoken to her about it and she insisted that she wanted to try 50/50 and this school." She will have a full week of school. You can ask her how she feels now. You can offer her the option of still doing the 50/50 split but with her trying the local public school in your town. Tell her what ever decision she makes, you will always be there for her.
If your daughter says she wants to go back with you and go to the local public school I would talk to your lawyer about getting some temporary orders in place till the divorce is finalized. Get this started before you move your daughter to the local school. this way you will show you are trying to support your daughter while also doing it legally in a way that you wife can't snatch your daughter back to her place.
You need to start pushing what you feel is right and not get blown around by your wife. You need to steer your ship and not let her do it. You need to let go of your marriage without anger. The anger is what will keep pulling you back into her storm. Blame the depression for her actions and get angry at it. At least you know it is a disease that is out of control within your wife right now. Focus on that and not the person.
