Mighty, has it occurred to you that your ex needs to finalize things with hww? Keep perspective - this is his mess. He NEEDS to take care of it. This is part of his growing up and finalizing his own issues.
I'm not in that position, but I would think it's in everyone's best interest if he cleans it up without anyone else helping.
She'll move on to her next victim before too long. Your ex may take a bath on the house and in other ways financially. It's a hard lesson to learn.
Let's see how he handles it shall we? And then wait a few days to see how it plays out.
