WS - so sorry you're going through this. Our stories have some similarities. Only one thought. It's hard to manage the situation and grow without some emotional separation. When we keep getting drawn back in, with the ups and downs, hopes and disappointments, it's hard to work on ourselves. All I can suggest is get some emotional space where you can - if it's GAL, fine. If it's leaving the house early or volunteering to coach sports for your kids, or church, hobbies, whatever. The thing about boundaries gives you some of this space - like a buffer so you don't have to react to every dumb thing she does.
