I just caught up on your thread and it sounds like you are doing well and focusing on being a strong, comforting presence for your kids. I can absolutely relate to telling your kids being difficult except that for me it was actually worse than BD. When I told them we had something to tell them, my D asked if we were having another baby. I just wanted to sob!
Unfortunately, I can’t offer much advice on coparenting. X Mr. GB and I get along well and he only has the kids when I go out of town for work (he stays at my house) However, it helps me and things have gotten much better with the passage of time. I do agree with the others that you need to set boundaries and your x needs to respect them. Will she? Probably eventually.
Welcome to the coolest forum on DB :-)
