I’m seeing her true colors

Hey everyone I, 21F have been dating my boyfriend 22M for 5+ years. With that being said I’ve known his family for a very long time and have grown close with his parents and other family over the years, they all like me and speak good about me as I’m very respectful and to myself. I, in general have a good relationship with eveybody. I often visit his house and sleep over on the weekends. Since I’ve gotten close with his mom she has been very nice to me but she’s always talking to us about pregnancy. She has told me how if I get pregnant don’t think I’ll be welcomed in her home, how she won’t baby sit because if I get pregnant it’s because I have a husband who can house me…understandable. She is just always on us about not making a mistake and stuff which I understand but again…we’re young adults of course we love each other and engage in sexual activities where ever we can. In her mind her son is a virgin and would ask us if we ever done anything but we deny as it’s nobody’s business but ours. His mom is very bossy and controlling she’s just alwaus all up on everyone business and always has her eyes peeled for anything. She’s also controlling to my boyfriend, he isn’t allowed to sleep over and she has told him if he does she will drag him out of my house, I also live with my family! They love my boyfriend and encourage me to invite him over, they know I’m protected with an implant and I’m open to them about my life as I trust my family. She also stopped allowing me to sleep over since she “heard” us, which I understand but it takes two, I’m also a long term gf. I’ve spoken to him about setting boundaries as we’re getting older and he has done some things but one night he ended up sleeping over since it was pretty late and dangerous at night. It was the first time he disobeyed her, she texted him at 2 am to come home and he ignored her. The next day comes around and he calls her finally around mid day. As soon as she picked up she just exploded on him saying how he knew she had a headache and didn’t care about her feelings and how could he do this to her if he wants to be free he can but to not bother her with things. She started to cry because he didn’t care about how she felt too and she was on speaker so I was hearing everything. She also was asking if I was with him because we were in his car and he said no, so she just went crazy. He was defending me and himself telling her how she’s being unreasonable for someone his age, he just graduated college and accomplished so much aswell. My bf also mentioned that why is it bad to come to my house and she stated because it’s embarrassing because you have a house here how he shouldn’t go to other peoples houses when he has one…yeah right. He also said well she comes to ours so why is it bad I go and she’s like oh that’s her problem like what does that even mean. So fast forward she basically said that if he wanted to come to my house to get his balls drained then go do that, it’s my problem if I wanna do that in my house but to not do it in hers. It sounded worse because it’s in Spanish and it’s like calling me moral-less basically. So I just stopped going to his house after that completely until recently were he invited me and I finally saw her but just said hi. Mind you I’ve always been sweet and talkative but I hope both of his parents realized it won’t be the same since I heard what she said about me, which she knows and my boyfriend said she was embarrassed by.

ANY advice on how to act towards her? I just don’t wanna be with a RBF the whole time and I feel weird being in her house but I don’t want to make my boyfriend like he’s torn between us since he’s an only child. I’m doing it for him and he knows I never wanna be in his house again, he’s been sad about it but understands my feelings aswell. He genuinely is a great guy and wouldn’t want us to break up over her but I just need any advice. I’m leaving out so many things but it would probably take me the whole night to list everything down.
