Should i cut off my mother?

start off with i love my mother and truly wish it was different and i wasnt considering this. My mother and i have had a hard relationship most of my life. Growing up i was physically and emotionally and mentally abused by this woman. About 8 years ago she apologized and said she was sorry about everything and wanted us to patch things up. Everything was going good until 2021. I gave birth to my first child a daughter. And since then itd been hell. She is 6 months old and recently we got into an argument because my daughter was sticking her tounge out. I was told it was rude and i needed to tell her it qas wrong right now before it becomes a bad habit. I did not follow her advice since its apparent its a phase. But this is a woman whose accused my fiancee of faking seizures to make me feel bad and not work. Laughs at his anxiety and says the way he sets out his pajamas for the week is stupid. Who says his anxiety happens cause hes to self centered. She accueses me of being in a lesbian relationship with my best friend cause we are close. She already has ruined my daughters first Thanksgiving by making my fiancee feel uncomfortable. I have attached messages from her from yesterday. It all started cause i havent texted her this week to see how shes recovering from the bronchitis shes getting over.
