Frustrated

My husband and I bought a house at the end of June with the help of my parents since they were moving in too while they supposedly get their credit up and save money. They said they would handle house payment for now, and rest of bills would be split in half. Okay, fine. They make more than us cos my dad is on salary, and my grandparents also help since they live here too. Well, we ended up paying the first month with what we had in savings. My mom transferred the $400 and kept saying shed get the remaining $482 back to our account as well because it wouldnt let her transfer that. Okay fine. Whatever. We have stuck to our part, and we even cover whole bills. As well as paying off a credit card I got to help pay for my moms dogs vet stuff that they maxed out. Still no $482. I mention how it sucks not having the almost $900 we had in savings in case we needed it for emergency with the house or whatever, and she gets shitty and says they have $5 in savings and like $50 in checking. Like what the hell. Dont say you're going to do something and not do it. Now we have $400 in savings, which isnt shit compared to the almost $900 we had. I am just so frustrated and I kind of wish they just didnt even bother moving in. Everything has to be her way. Cant bring my sons toys down to the living room where he spends most of his time. Have no where to put his bed because hes supposed to share a room with my little sisters. Probably going to end up squeezing my family of soon-to- be four in my husband and I room... they have pretty much filled half of the basement with their things, and the other half is going to be for my dad to have a workshop and then hopefully my husband can get a little hangout spot too.... not that we really get to have friends over... and my husband isnt even allowed to drink really because my dad doesnt like it. Dont get me wrong. I love my parents, and love having them here, and the help with bills is great, but not sticking to what you say and spending the $482 you swore would go back to our savings account is beyond shitty. Should have been upfront and just said you weren't going to do it. Now we have to try to slowly build it back up so we can put up a fence and have some emergency money... but we might not even be able to do that with paying everything that needs paid, because I also have a $200 hospital bill from my 20 week ultrasound I have to pay off somehow and it is all just frustrating. Granted I'm basically 31 weeks pregnant, so part of this may be hormones, but good lord. 😭😭😭😭😭
