Oh boy! I know how you feel! I've had those kinds of reactions. Hoo boy, and how!!!!! Look, it seems like your H is a cake eater. He wants you to hang around and give him emotional support, while he figures things out. Rather selfish, but then we know they are not themselves. To ask your LBS to be the support while having an A! Just boggles the mind. I know that I could never tolerate my H talking to OW in my house. I told my H the same thing. It's a matter of respect to me and my children. Anyway, I don't know what advice I can give you - just know that I feel for your sitch - been there, done that, and know what you are going through.
Only you can know when it is over for you, when you have reached toxic overload. You are right when you say you need to take care of yourself. Your children will be happier if you are happy.
