Agreed but she said in the past her MIL has debts because of someone who said she will be getting lots of $$$ if she gave him some $$$. Turns out the lady went into a huge debt and the sons sold their wives jewelry to pay it off. Unacceptable! Not just that, every now and then she has some issues. I would seriously suggest moving out.
OP and family can go visit them but at least she can keep the mess out of her life and her kids.
