In-laws

My fiancé, my daughter, and I are staying with his mom and her boyfriend and his little sister. Our room is a separate part of the house with a bathroom so I have to go outside to get to the part of the house with the kitchen so I like to be able to make my food and then go back into my room with the baby. But I’m not allowed to bring any food or any drink except for water. I’m not even allowed to make bottles in there but I’ve started putting the formula powder in those to-go containers and putting water in the bottles to be able to make them there with no mess. However, while we’re not allowed to do that (they were out of the country for a month so we did while they were away lol), they keep a compost bowl in their kitchen with gnats flying around it. I’ve found her clean bottles with ants in them. Our room has never had gnats of ants. Just today her boyfriend left a plate with a partially eaten apple on it sitting in the table. Even though the sink and compost bowl are 2 steps away. We don’t have the money to move out at this point (were working on it though) and I don’t want her around all the gnats. They literally worry about our mess and say cps would take our daughter because we didn’t have actual sheets in our bed and the mattress cover was dirty and because of the clothes on the floor. I’m 100% sure cps has much bigger things to worry about. Her clothes are always clean, she’s bathed, fed, cuddled. She’s starting to laugh and smiles a lot and she’s super chunky. I feel like if cps would take her over anything in this house, it would be the rotting food in the kitchen that we have no control over. I’m even fine with the compost thing. They’re starting a garden and that stuff is good for the garden and I know composting is better for the earth. But when you’re done cooking and while you’re cleaning, go ahead and take it out and then rinse the bowl so there’s not so much bacteria everywhere. My fiancé was cooking for us and it was getting close to sunset so I asked if we should go on our walk instead of waiting for him and i said it calmly, I knew he was doing other things it was just part of our conversation from earlier. And his mom got on my ass about how he works all day and he’s cooking for us and all this other shit as if I’m not grateful for him and as if I said it rudely. (He did stand up for me, he does not lack there). Sorry for the rant. It’s just been really bugging me. I know she only started to like me when I got pregnant so she could see the baby. I know that.
