my sister in law moved in with us!

so my husband and I had just gotten our own place, we had been in the house for two months he is 5 years younger than me. his sister just separated from her boyfriend they had been living together for 5 years. when my boyfriend introduced me to her she made a face and bearly said hi.we attended a wedding they went with us and he sat in the middle of us. she was hung to his neck kissing him holding his hand his leg playing with his hat. so I was like ok maybe she need attention. I went to the restroom and honestly I took long on purpose I felt like I didn't want her to be upset I was there. idk plus my boyfriend now husban was ignoring me. she has never liked me. I was pregnant when she moved in. I had a doctor's appointment and he didn't go with me because he was mad that I told him she she can only stay for 2 months, so he didn't go with me to the appointment. instead he took her to eat. when he came back I was already home didn't even ask me how everything went. before she moved in I was happy. we cooked together we cleaned. we would go on walks. I was 8 months pregnant and I was still cooking for him and his sister because if I didn't ask her to eat what I cooked I was the meanest bitch ever according to him. we got in a flight because she doent do anything around the house and I was tired of it. we argued and he left the room to sleep wit her. when I went to knock yeah I should of just leave it I know. but i knocked (for 3 min) she bearly opened the door and said he was asleep. so I went back to my room. we talked about it I told him didnt him ignoring me he just said ok it wont happen again. so we argued again about a phone call he got and he got mad when i asked him. again he went to his sisters room and then they both left outside to talk inside his truck. days passed we talked about it. my baby was born everything was good in the hosital I come home there is dirty dishes she hasnt clean her own mess. I star cleaning she comes out and asked me you need help! 😡. two weeks passed I'm trying to tell my husband in a nice way I need my space and I want his sister to look for another place. he gets mad but says ok. He got a text I asked him turns out it was his other sister texting him why did he kick out the younger sister out of the house. we were arguing when I was heading out of the room my sister was knocking on the door I opened, I tell her I cant take this the cleaning the cooking for both of them. plus taking care of my baby. he says hes leaving because he cant stan me bitching about his sister my sister tells him "well leave" and by this time is his sister is in the kitchen telling my sister to gtfu out her brother's business. my husband told her to be quiet. my sister in law texted my sister on fb. telling her how disgusting my sister looks fat and dark. she said for my sister never to come to my house or she was going to kick her ass. I just want her out of house. but I'm afraid if I tell i him to move out immediately he'll think I'm a bitch. she asked to stay for 2 more months it's been 9 months at my house. I clean and cook and buy groceries and toiletries everything. she has only cooked 3xs max. and every where we go she has to go. I'm sick of this
