I told my MIL to mind her own fucking business

My MIL is such a shitty person. She belittles me. Calls me an unfit wife, talks down to her kids. My husband doesn't stand up to her because she caused so much trauma. He is in some intense therapy because she is the reason for his suicide attempts. Oh you want to know her stance on rape? She said 70% of the time its the victims fault. For my rape it was my fault because she said I dressed like a slut. For my husband's she says its his fault for boasting about being bisexual. So that's what I deal with. I'm due for my first baby in September and his mom is mad I'm not breastfeeding. I don't wanna breastfeed and I can afford formula. My business my choice. She had the nerve to call me a bad mom for poisoning my son and Saud he won't love me because I won't be breastfeeding to form the connection. Like HUNTY! You son was breastfed until 2 and hates you! But she kept pushing me calling me a selfish shitty mom. I can handle it. Its when she starts talking down to my husband that I can't. He's overly sensitive because she destroyed his self esteem. So I said "Beth, how about you shut up and mind your own fucking business. Its our baby, not yours". She couldn't even find words! In laws.... So much fun..

Edit: Why we stay around is a guilt thing with my husband. When he was 16 he got upset with bullshit she had done and left. She ended up having a shelf or something fall on her and ended up.I'm the hospital. She told my husband she kept calling his name, but he never came and she knew then that she would die alone, blah blah blah
