Husband just shocked me with horrible “joke”. Im in pieces

We have struggled with secondary infertility for a long time. My brother in law is now expecting. My husband just said to me, “we should give him all of our baby stuff from our basement”. How could he say that to me?! He knows my pain. He knows our stuggle. He knows the countless tears I have shed over this journey. He yelled at me and said it was a joke and I need to get over it. It was just words. I don’t even know how to be right now.
