Manipulative mother- while I'm pregnant

sorry for the long rant but I need to vent and maybe get some advice.

I'm currently 33 years old, no longer a kid, I have a job, pay for my house and my fiancee is still in the picture. I found out 3 months into the pregnancy that we were expecting and I'm now 25 weeks pregnant. My mom has always been very old fashioned and hard to talk to. If I wear something she doesnt like, she will laugh as if she was making fun just to make me feel bad bc she knows it will make me go change . If I try to explain to her why I want something...let's just say I want to go stay w friends and go to the beach, she will tell me how dangerous it is and make up stories and then start crying if I say shes overeating.

Throughout the years it seems like any guy I dated , she didn't like and always had a reason for not liking them even when she didn't even give them 5 seconds of her time to get to know them.

I feel so frustrated bc I pay for my house and allowed them to move in w me years ago now I'm pregnant and want to start my life and decorate the nursery. I did not kick them out nor am I trying but she has my grandma and aunt in the room I need. she said she was going to bring them here while the situation in Puerto Rico improve. is almost a years later and it seems shes planning to keep them here without even asking. She talks non stop about my fiance when she doesnt even know him and she doesnt know him bc every time hes around, she makes him and myself feel uncomfortable and she will not even bother to say hi to him. well, now that she knows I'm pregnant, she keeps talking nonsense that stresses me and she knows that and she lives in my house but wouldn't even talk to me . close to 2 months of her silence treatment which she has done in the past to make me feel guilty. I used to leave everything and please her when she did that but I cant just toss away the family I'm trying to start to make her happy.
