My mother-in- law hasn't liked me from day one. She told me to my face that she never liked me and that she wished that my wife married her prior boyfriend . She's colder than ice.
I only say hello and goodbye to her. I have never called her. I never visit her home over the holiday's when my wife and kids are invited. She has been in the hospital numerous times. I have never visited, sent a card or called to see how she is doing.
My wife and I argue all the time about her mother. She will never understand why we dislike each other.
Your husband sounds like a wonderful man to let you decide if your kids can see your parents. He's not missing much when someone dislikes you for no reason and is not welcome in your parents home. Worse is that your mother bad mouths your husband.
Since your mom has no respect toward your husband you don't owe them the rights to see their grandkids!
