If you didn't tell him that you have postpartum depression and that's why you are not caring for the baby properly, I can understand why he might be upset. There is never an excuse for calling you names, but if he is having to pull more than his 50%, then he is probably over tired and stressed out and struggling himself. Since you are not being honest with him about what is going on with you, he doesn't have the importation he needs to be able to understand you and show compassion. He just sees that you are not caring for the baby and he has to pick up the slack. If he is your husband, why aren't you being honest with him? It's really hard to make a marriage work if you are not telling your spouse what is going on.
