I think I might get my name off the credit cards and open one in my name only. This way he is ruining his credit not yours. Do what you feel is best for you. Can you handle him going crazy again? Can you handle the threats AGAIN? Think of what would be best for you and your girls. Do what you feel you have to for you. Turn this over to your HP and he will guide you on the correct way to handle this again.
Stay strong and take care of YOU!!!!!!!
