I don't think he is hitting bottom - I think he is just continuing to try and maniuplate you. He's wants to try and move the focus off of the fact that he caused this, he's the one who left the marriage and now he's doesn't want to deal with the consequences. I don't know what you should do. If it was me I would be inclined to go and just pick my kids up and get them out of there. If in fact he is sitting there crying like a baby, you don't need to have Nathan and Sydney traumatized by that. Again - I am sorry he is putting you through this after everything else he has done.
