Sun, I'm sorry that this is such a mess. Well...I'm not surprised to hear that he's using the kids as the excuse for not leaving. That excuse is about the worse I've heard thus far. As for the loan, it's his problem.
Now that the child has enlightened you and the kids about himself, you will now need to go w/your life. Time to do for Sun. In other words, treat him as a roommate and nothing more. Sun, you can do this. Once he sees that you aren't worried about the way he's acting, he may very well change his tune. Be careful if he does that. He's a miserable person and he's not happy w/his life and he sure as hell doesn't want you and the kids to move on and enjoy life. He so reminds me of Scrooge.
Please take care of yourself. Sit down, chart out how you want to live your life w/o him in it for the time being and do it.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
