BTW, H moved out in April and is living with his parents (no rent, no utilities, no grocery shopping, no laundry) Mommy is taking very good care of him. I love my mother-in-law, but she cooks him dinner and does his laundry. He truly does have the best of three worlds.
His mother knows he is having an affair, and yet she treats him this well? Do the in-laws support your marriage? What was their response when you exposed to them?
They are enabling him; my guess is, maybe she's done that his whole life?
