My mother-in-law is dating this loser. I've tried to point this out to my wife but she just says it's none of our business. I love my m-i-l and don't want to see her hurt. Do I just wait to pick up the pieces?
It seems there are forces at work from before you were with your wife that you may not know about. Regrettably, you just may have to take a "wait and see" approach. It certainly would seem your wife would want to protect her mother, but maybe she knows her mother will not listen. The only exception would be if you had concrete evidence.
