Would you be mad if you told your husband that you have just missed miscarried your twins yet he doesn't bother to come home or check in on you?

I called my husband today and told him I went to my scan and told him that we have had a missed miscarriage of our identical twins. He is setting up for his dad's unveiling in the weekend, yet he hasn't asked if I'm OK or come home, I was expecting him to be home when I got home for support. He's been there for a good 7 hours helping his siblings. I'm upset at him, is it valid to be upset at him?
