MIL from hell

I've had enough with my MIL. Today my husband has officially cut all ties with that devil. Shes done so much sh*t to us that if I said everything it would take days to read. But to make this short ever since shes met me she never liked me. She's always told lies about me to my husband when we were dating. She always tried to separate us even going to the extent of bringing her friends daughter and try to make him date them in front of me during holiday parties or events. All of those things I would let them slide because well that's my husbands mother (unfortunately) but today was the last straw. My husband and I have been trying to conceive for the past year and we found out we are pregnant! When we told her the news she straight up told my husband "I hope it ends up in a miscarriage so you can finally get rid of her. If not that thing wont be accepted in this house. And you may want to take a DNA" at that point I wanted to kill her. My husband got up told me to get in the car and told her he didnt want anything to do with her ever again. How can people be so cruel and evil in this world? I just had to let it out because it's killing me inside
