The thought of this makes me feel like I need to throw up.

I probably hate BM more than anyone I have ever met before. She's just a nasty miserable person.
ExH hasn't been around for BS but is around for xSD.

Finally we arranged a meeting for him to have BS but he also currently has xSD. SO he's been spending time with both of them.
Tomorrow I am meeting up with him to pick up BS but at the same time, AND PLACE, he is meeting with BM so she can pick up xSD.
