I'm feeling really upset

My husband messaged this girl that he knew a few years ago to congratulate her on having her baby. They hadn't talked in a long time but ig he just wanted to say congratulations but that wasn't all they talked about. See I've never wanted kids and I was under the impression that my husband didn't either. In the messages she asked if we planned on having any and he did no and that I didn't want kids and she asked if he wanted kids though. He told her he did but he knows I don't want any. She goes "So you gave up having kids for your wife?" And he said "No. I was aware she didn't want kids before we even started dated. I've accepted I'm never gonna have kids." Qnd she goes " I just think if a good person wants to be a parent they should be able to." And then he said "Eh. There are other good things to come in life besides having kids " He's never once told me he's wanted kids. Not ever! And this is how I find out he's wanted kids for idk how long! Maybe I'm overreacting but I just feel hurt and stupid because I thought we were on the same page.
