Just annoyed

My SO thinks because I don't have a job that I should be the only one doing things around the house and now our roommate thinks the same thing yet his girlfriend doesn't have a job nor is she pregnant . If I say anything like I did finish this or that because my feet or back hurts he tells me I complain too much and I need to get over myself .  He always wants to pick a fight and throw in my face that he pays the bills , almost like he's holding it over my head . It's almost worth moving back in with my mother ..
