idk where to turn

Here lately I just get more unhappy everyday when it comes to my relationship don't get my wrong I love my boyfriend but just sometimes I wonder if that's enough. We been together for two years. He has two kids from a previous relationship we have custody of them. He asked me to quit my job here about two months ago so we wouldn't have to waste money on child care anymore and so I did so I'm with the kids 24/7 barely get a break. I always make sure house is clean always cook dinner. We been fighting here more and more. He says that he is just joking when he makes rude comments and says I just blow it out of proportion and when I mention things about he does nothing for me he blows up at me and I try to make him understand that yea you may pay for everything but that not what I mean I mean emotionally u don't do anything I mean shit he won't even run my back when I asked cause he is too tired to do he says I'll do it later well later turns into a week a week turns into a month and on and one but when he wants a back rub or foot or something if I say no he gets mad and won't take no for an answer.
