Give him one more chance to do the right thing and support you against his mother. If he won't, he is a mama's boy and needs to go back to mama. You don't need another child to raise.

Well, pretty wimpy advice to the wife with the MIL problem. This has obviously been going on for some time and the wife HAS spoken to her husband about it. If talking to him one more time doesn't have any effect, then kick him to the curb. Hubby won't cut the apron strings, so it's time to go. Does the wife want her kids to see it's OK to disrespect their mother? Sometimes it's better to be a single parent than have an unheathly relationship.
