Hi I Just Had A Baby And I Feel Like

Hi i just had a baby and i feel like i hate my husband. Ive read that it is normal but it also says try harder if both of you are making an effort. Well my husband works but my daughter is almost 3 months old and he hasn't even changed a diaper. There are other things that are bothering me too and I've tried to talk to him but it seems like he doesn't care. What do i do?
