Advice

My boyfriend is the only one working right now. He thinks because I don’t work I should be responsible for all house duties, I’m currently 9 months pregnant and have bad pelvic pain, shortness of breath and back pains. I’m trying to organize and prepare for baby and just want his help, but he just keeps saying since I’m home all day why can’t I just do it? If I do clean the room, when he comes home he makes a mess of the room.
