Am I wrong?

I had a baby a few months ago and my boyfriend thinks I have PPD I went to the doctor and they sent me to a counselor or told me it wasn't PPD but regular depression along with a mixture of other stuff. Well my boyfriend has been taking care of our child while I go to school. He complains that I never help but as soon as I get home I am the only one that takes care of the baby which is not a problem. But he tells me I do nothing and I am lazy. He complains about everything he goes through and make me feel like I am lazy and do nothing. While he was going through hard times I comforted him and took care of him but when I go through hard times he is so hateful and rude to me. We have been together for three years and he got ruder to me after I had of child. I'm just wondering if I am doing something wrong or do I just need to suck it up.
