Mothers-in-Law tend to have that sort of behavior in common. Don’t feel even a tinge of guilt; I sometimes wish I’d done some things differently where my MIL was concerned. (She’s been deceased a few years now; was 88 when she passed away.)
You know, my mother-in-law passed away many years ago when my young wife and I were expecting our second child.
My wife was about six to seven months along, and I remember being very concerned with her and the child’s health. I did my best to think of them first. I did not want her to go spend a lot of time spiraling downward at that point in her pregnancy.
One thing I regret, was not going over to visit her mom on my own to give her moral support. She was more sick than we realized. The family was badly broken. She did not get the support she deserved, and I would never have meant to short-change her at a time like that.
I don’t care if the woman treated me like dog poo, when she was very ill, I would support her.
That is is my regret.
