I'm going to keep my mother in law at distance from our family.
Why would you keep your mother in law away from your family?
I'm tired of her bullshit, she's an evil woman.
Not always getting along with a mother in law is to be expected. It's understandable to want to protect your family members, but you should talk to your partner first and let them know how you feel. They may suspect your true feelings if you don't.
I'm tired of her, her questions, her personality, everything.
You need to talk to your partner and tell what exactly your problem is with her mom. Your resentment toward your mother in law will cause problems in your own relationship. You have to find a way to get along with your mil.
