Annoying Support System

Have any of you other women had any issue with you partner not really feeling all too supportive. I mean, I know my husband is the bread winner for our home being that I only left my job due to an over stressed work environment for me, and the baby. But he doesn't help me do a damn thing when he comes home, and then pretty much complains the ENTIRE time he's home by huffing and puffing everytime I ask him to do something simple. Like taking out the garbage. Or cleaning out our bathtub since I can't get my belly out of the way to get in there and clean it (not to mention the cleaning products). As well as, any normal thing that may cause me to strain myself at 32 weeks pregnant. I have been having really bad back pain, and restless leg. I don't feel like I ask a lot of him but he should have known the further along I get, the more help I will need right.?? Not to mention doing things for our 6 year old son. But then he has the nerve to ask for sex when I do all the cleaning,cooking, shopping, etc. Am I overreacting.??
