Am I in the wrong?

So me and my bf have a two month old daughter, and before she was born the last two months he went and hung out with his friends lots because he said he wouldn’t have much time once our baby comes and he’s working. Which I was completely fine with I encouraged him to hangout with them then. Well now she’s arrived and he still just goes and hangs out with his friends and I’m left looking after her by myself. Am I being selfish for wanting him to help me?
