Did your husband mature when your baby was born?

I can imagine that I’m not a perfect person. But becoming pregnant has made me look at myself and work on my imperfections for my son. And that’s where I want my husband to do as well. But it seems like he just wants to go with the flow and sees nothing wrong with the way things are right now. I’m not gonna get into our personal life but things need to change. Did anyone‘s husband mature once they saw the baby? My friends keep telling me that you’ll understand once our son gets here.
