My husband just told me he doesn't want kids

So my husband and I will have been married for 2 years in May we have been together for 4 years. We have been friends since we were 16, and I just turned 26. I've always wanted kids and a big family. I made that known to him too many times to count, and he told me he definitely wanted a lot of kids too (before we got married). Now last night he says he could live without having kids and he would only have one because I wanted to. That's upsetting to me because so I really want to have children with someone who doesn't actually want them? I'm so scared because kids are a non negotiable for me. I'm angry and hurt because I feel like he lied to me. I don't know what to do anymore. When I try to talk to him about it he just writes it off as me being dramatic. Help please?!?
