My husbands ex is crazy. Any ideas on how to deal with it.?

Do screen shots of all her FB harassment and print them out. Save every text message, e-mail, voice-mail, letter, etc. Use all this to get a harassment restraining order on her for yourself. The police will decide if he really strangled her or not. Who knows which one of them is telling the truth on that issue. Legally she is not doing anything wrong by having him pick up the child, and if you want something different he will have to go to court about it. But seriously why not just have them exchange the child at the local police station. That way no one needs to get all jealous and they can't beat on each other. Honestly, I think he is probably nuts too, otherwise he would be handling this in court not having physical conflicts with her in Walmart's parking lot. They are both dysfunctional, and I feel bad for the kid.
