when you hate your boyfriends family ☹️

Miranda
My boyfriends sister is horrible. They're from out of the country, Cuba, and haven't had the *best* life getting in their feet here but have always had each other. From the first day me and my SO went on a date he's told me about how she's been to him but he truly has a heart of gold. His credit is ruined from letting her out things under his name and then deciding not to pay it anymore only to leave him with a fucked up credit score which is now biting us in the ass. They were living in an apartment together with her 4 kids and he was helping her pay the 1000$ rent. So then they move out into a house, with a 2000$ rent where my boyfriend was only supposed to be paying 500$. Shortly after I got pregnant and somehow we ended up paying 1000$ or more for rent. He's always helped her whenever she asked because he cared more about the kids. Wanted to make sure she was paying her bills so they were still being fed and taken care of. I have never liked her I have seen who she truly is from the first time he told me about her. I love him so much it bothers me to see her take advantage of him and he's blind to it but becoming more aware. We have fought a lot about having to help his sister, she's 28 with 4 kids and she barely works. She depends on men to pay her bills and take care of her. And the two men she's been with in the last 8 months both somehow ended up with no job. We finally moved out into my parents house, and so far it's been so nice to just pay OUR bills. We even were able to money away so he's able to take a week off when she's born. But the engine on his car blew up so he had to buy a new car 😞 and then he lended her 500$ that she said she was giving back a few days later... well she kept dodging him and finally he called his mom who she owes money to for watching her kids and apparently she told his mom she wasn't giving him shit back. So we lost 500$ 10 days before our daughter is due, after we just had to buy him a new car. I feel like she's being spiteful that we moved out, because she's done nothing but cry and try to make him feel guilty for it since we've let her know, (in December, we didn't move until February knowing she couldn't afford the rent there) and she moved a random guy in and is only charging him 500$ for the same room we were paying 1000$ for. I'm so disgusted by her. I don't even want her around my daughter but how can I even say that to him? He has taken such good care of me and our daughter already and she's not even here yet. I don't understand how you could do that to your family. If my daughter wasn't going to be here in a few days I might have felt differently. Not to mention we pay the internet bill at her house still 😒 thankfully we had money put away because we wouldn't have been able to pay our other bills... so frustrated what do I do?
