Stressed

Im 29 wks and iI don't know what to do to get it through to my SO that i need attention, he so mad because this pregnancy has left me with no sex drive so he thinks I'm messing around, he bothers me every day for it and makes me feel terrible if i don't want to, tells me he's bored and unsatisfied with me. He won't rub my feet or back even though i tell him every day that im in pain, and when i ask he tells me i should be rubbing his because "he works hard every day to pay my bills" , he's constantly out with his friends, not coming home at night,he did this during my last pregnancy at the end too so i think it's partly cold feet about having a new baby, but still, i need attention and im not getting it, i just want to cry, i never felt so alone during a pregnancy, and this is my fourth, and i was single with my first two (they were surprises and i didn't stay with the men). I want to leave but i cant. I went out to eat with my mom for mothers day today and he made me reheat his supper in the microwave when i got home as he sat at the table playing on his phone, because that's my job, why can't i get a day to myself! Then he even left his dirty dish in the living room and my son got to it and spilled it all over and he refused to pick it up, and went to bed said again that's my job not his. What am i to do. I'm heartbroken and lonely and i want someone to care about me. I have 3 boys a pregnancy and a grown man to take care of. where's my love?
