I don't want my MIL seeing my baby

I know this sounds horrible but I really don't want my soon to be mother in law seeing my baby when it's born.. my boyfriend and I have been together almost three years and she's been pretty much supportive all these years. My boyfriend and I have not gone to college yet though (neither of us have felt ready and would have to travel far to college cause of where we live) and in her mindset she thinks we both need to go to university, become doctors and not live together until we're in our thirties and completely own a house together🙄 when I told her I was pregnant she said I was ruining hers and her sons life. Then after he told her he wanted to move in with me this summer she messaged me and completely freaked out. She was so rude and disrespectful and even said I need to get an abortion (I'm 16 weeks already and I would never even consider that) I told her if she thought she could treat me like crap this whole pregnancy then see my kid, she's wrong. She then said I was being dramatic and blah blah blah. She's also saying stuff to my boyfriend, trying to get him to leave me and the baby. She's always been really controlling and manipulating. I'm so upset with her honestly and I really don't want her to be around my baby but I don't want to hurt my boyfriend. What should I do? Am I being dramatic?
