Shitty in laws

Im so tired of them thinking they can just keep disrespecting me. I wish I could get away from it sadly I can’t because I live with them. Me and my SO had an apartment but unfortunately it burned down and his parents lived in those apartments too as well as his older sister. So we rented an apartment with his parents to help them out because everywhere was too expensive for them. So what we rented was a 2 bedroom , I was thinking half of the apartment should be ours right ? Since we pay half the rent. NOPE. Whatever I just store everything that belongs to me in my room and I accepted it . My SO siblings live here also a 17 year old brother and 2 younger sisters . I thought at first cool maybe it might be fun living with a big family but I should of known better. My mother in law says the meanest stuff to me when my SO isn’t around .. last week she told me I’d rather raise cats then have kids.. why would she say that knowing I struggle with infertility and I’ve tried so much things to get pregnant and my cats have helped me cope through this , I was crying cause I was so hurt and all she did was laugh. Then later when I tell my SO what she says she says that she never said that and then it makes me look like I’m making it up. So last week my sister law shows up with her kids and her man and as soon as they walk in he doesn’t say hi he tells the kids go kick the cat .. Then says “ima fucken kick that shit if it comes near me” and first of all I wasn’t even aware they were coming I would assume if you live with someone you should give them a heads that someone is coming over and second how do you walk in someone else’s place who’s letting you shower and cook there and say that ? but whatever that just really pissed me off because he’s always saying what he wants and no one ever says anything so he just continues. Then my mother in law tried to stick up for him saying he didn’t mean it like yes the fuck he did and there’s just certain things someone shouldn’t say well anyways I ended up telling him off so my mother law got mad and hasn’t spoken to me in 3 days but at this point I don’t care . It’s just so awkward so I just stay in my room it’s weird cause when I walk to the kitchen she stares at me. There’s just so much more stuff she’s told me like she doesn’t think I should be with her son . But if I write everything it would be a novel lol 😂 but yeah my father in law is cool it’s just my mother in law and brother in law too he put us through hell we always had to bail him when we gets and trouble and still has a shitty attitude with us he just got off probation and my sister in laws man who doesn’t know when to shut up. Sorry for the long paragraph I just really needed to vent 😭😭
