Was going to add, but couldn't. My experience?
My father's mother (my Grandmother, obviously) was a very demanding woman, very. My father was an only child. When my Grandmother telephoned and needed something she expected my Dad to jump - immediately. She had opinions on how/what/when/where, whether she was asked or not.
She made helpful suggestions to my mother - suggestions which my mother neither needed nor wanted.
I remember how she meddled, even though I was a child, and I've patterned my "in law" behavior in the opposite direction.
Why my Grandmother's behavior? I have no idea. Part of it, undoubtedly, is my mother married her only son.
I only know when my Grandmother arrived we put our seatbelts on (so to speak). I know how many times my Dad got caught in the middle until he finally told my Grandmother to butt out.
She did and thinks quieted down.
And I loved my Grandmother - but I knew her feelings about my mother.
I also note that OP has dealt with depression issues - how does that play into all of this? https://www.askmehelpdesk.com/childr...do-734761.html I do notice you call people "Sweetie." Is this part of the problem with a PR daughter-in-law? (My nephew's wife is Puerto Rican and I find her to be somewhat reserved. She is very warm, but she is also very "proper.")
