Do nothing more. Keep the stock account intact as it is, there are compromises you can make for S and his education perhaps. In the future, there is no hurry.

The ball is no longer in your court. You handled the interaction very well indeed, let her keep on with the cheese less tunnel until she finally tires of it. And she will, eventually. No volunteering or being generous will help. You have set your boundary, this was the way she chose, you agreed. W hasn't had the result she wanted, you offered to modify, she flaked. Now wait, keep quiet, repeat the boundary if needed but don't offer anything further.

Keep on becoming only a man a fool would leave.
You need time and you have it
