husband not around for our newborn

Our baby is 5 days old. My husband had honestly been great. He even stays up and helps watch the baby so I can sleep. He went to work today and when he came home he said he wanted to go play basketball. I asked him not to go and he still did. He said he would take care of the baby all night but I still have to wake up every two hours to feed her! He's been gone for 4 hours it's almost 11pm. I didn't get a chance to shower and I've ate one today. Am I being over sensitive considering I just had a baby or do I deserve to be upset. I just feel like my whole life just changed and he still gets to do whatever he wants and is not thinking about me already. I guess it was nice while it lasted.
