Need to vent, and have some questions!

My boyfriend and I have a one year old daughter, when I found out I was pregnant with her, family wasn't too happy, but around April of last year (I was 6 months pregnant) my boyfriend moved in with me at my parents house. There were so many problems especially with my sister and brother in law. My boyfriend and I had gotten into some verbal fights before he moved in (he's also had a rough past before we met) and that's why my family isn't too fond of him. They would always give him the could shoulder, he never felt comfortable in the home and I was always put in the middle. On top of that we were paying $650 for my very small room, we had no cable (only our Xbox) and we bought everything for the home that my sister would then steal and leave us stuck having to always buy more. Dometkmes we didn't have the money to even pay rent bc of that. My daughter was about 7 months when my BFs parents asked us to move in with them, room is bigger, we don't pay rent and have access to cable and everything. His family is great but I'm stuck cleaning their WHOLE house, they say I don't have to but they leave a huge mess and my mom always taught me that everything needs to be clean everyday (they don't clean at all😒) his little sister is on summer vacation and makes a mess even after I clean and I clean it up, it's even harder since I'm 15 weeks pregnant with my second baby. I've told BF and he says to stop cleaning, so I did but I can't help this huge nasty mess. On top of that my daughter keeps getting rashes and so do I, I think it's from this home bc she and I never had it before. I went to visit my parents a couple days and I miss my home so much, my moms cooking, the quiet neighborhood (BFs parents live in a really ghetto neighborhood, we hear gunshots and cops everyday) I was able to do what I wanted. When I visited my parents I was actually hoping they'd ask us to move back rent free but I know that wouldn't happen. But should I bring up to my parents and BF? The only problem is my sister would still live there, but should we just ignore her and move back? I'm not sure what to do, I wanna move back but I have a feeling parents won't let us stay rent free and BF won't like the idea bc of how they treat him. Need help!😔
