It's not just my job!!!

I am beyond livid. I am so tired of living with my fiances dad and step mom. Before I moved in they were capable of handling shit around the house without help because my fiance never did anything. One of the stipulations for me to move in was that I would help around the house which I do quite often, just not everyday. Wednesday I got yelled at by his dad because he came home to dirty dishes in the sink, the trashcan full, and the dishwasher full of clean dishes and told me that I'm supposed to be helping around the house and if I didn't start I would be kicked out. The clean dishes in the dishwasher was from me and the night before the lid was off of the trashcan and full so his wife could've taken it out like I thought she was going to. That day I also was cleaning, folding my loads of laundry, and gathered trash out of our room and our bathroom. The next day I made sure to empty the dishwasher and fill it back up. We'll lastnight we had a friend over and his stepmom barges in and was like "you couldn't bring the fucking trashcans in off the street, what the fuck did you do all day?" Looking directly at me. I asked my fiance if we could leave and go somewhere because I was pissed off. All morning my fiance has been texting me from work trying to wake me up telling me I need to clean the room so he doesn't get bitched at because if he gets bitched at he's leaving and not taking me because I was supposed to clean the room. And hes pissed off at me because he's the one who has to deal with it when shit doesnt get done. I'm so tired of this shit and just needed to get it off my chest. Maybe someone could she'd some light on my shitty situation?
