Husband acting weird

Our baby is 10 days old and he’s been acting really off. Like lethargic and depressed almost. I never wake him at night to help me with the baby. He told me he’s stressed at work. Today he said he has to get out of this house and he’s mad at me because his friend is having a party and I don’t feel comfortable taking her around a large group of people. Yesterday he wanted to go out to eat and I told him I don’t want to take her in public just yet. I feel he is being selfish and thinking of what he wants rather than the health of our new baby. I told him today to go do something and go to his friends party tonight just him and I’ll stay home with the baby and he said he doesn’t want to go alone. Am I in the wrong?? Help!
