My husband hates being a father and I’m beginning to hate him

This is my first baby and she is literally my whole entire world yet all I endlessly hear is how he hates having a child, how his life is so restricted and how if he had a choice he’d go back in time and never have made this decision. At first I thought that he was just getting used to it and to cut him some slack but we’re 5 months in and no change. I don’t wake him up in the night, I do every bedtime, bath time...you name it I do it, yet still I hear the same thing and he doesn’t seem to understand why it’s upsetting. I seriously am beginning to hate him...am I being unreasonable for this to affect me so much?
