She sounds like my Narcissistic mother. They feed off controlling your life and smear your name if you don't let them.
Facebook has groups for daughters of narcissistic mothers. They are textbook. You'll know for sure with more info. Best wishes
I agree with the above post. Ground rules need to be established. My father in law feels that he can tell us how to raise our children....so if it's not nipped in the bud, the issues get worse.
Try too calm down sweetie. Its natural for your mom to feel that way. But as in disrespecting the father of your child is not it. Maybe you should talk to her and say that your not choosing side but regardless your gonna be with your baby's dad. Whether u like it or not. Just be respectful about it. But try to understand both perspective . And on the other hand make sure he's not disrespecting your mother as well
