I always feel a pang of sadness when someone doesn't get along with their mother-in-law.
Mine was wonderful. She was Mennonite when I met my DH, and she welcomed me into the family right from the very beginning, when she very easily could have tried to break us up like their "church" was trying to do.
She and DFI lived right next door to us and we never had problems with them trying to interfere. Sadly, she passed away 8 years ago after a lengthy and courageous battle with ALS.
I still miss her...
