feeling unappreciated

My boyfriend and I just recently had a baby she is soon to be 3 months old. We got into an argument this morning over rent and bills. He says he feels pressured to pay for everything and that I don't do anything to contribute. He pays $537 in total that's including rent and bills. I pay for all the household items such as toilet paper shampoo and everything a house needs I do coupon for these things it takes a lot of time and dedication to get the prices I get I also buy the baby's diapers wipes and buy the groceries. I do sell stuff as well to make money to pay for things I want or need. I feel as I help out around the house being a mom and taking care of the kids is a full time job.
