My great grandmother died today and my husband is being a dick

Im due Christmas. I spoke to my great grandmother last week and she said I know its my time. I just wanted to say take care of that baby... so she knew she was going soon... but it still hurts no matter how prepared you are. She has been Covid positive for 2 weeks and 91 years old. We wanted her to make it but we knew the possibility was thin due to her already being 91 and having severe pneumonia.

My dad called me at 5:56 and I was driving my husband to his boses house to get his check. So I was trying to focus on driving threw tears. When I got off the phone with my dad so he could call my other siblings. I told my husband what happend and his response was " im sorry baby... whats for dinner ? " I wanted to scream but I didn't i just said I don't know. His boss lives right around the corner. After he got his check we were driving home literally a 10 minute round trip... so i still haven't processed it. It's now 6:30... so i just found out a little over 30 minutes ago... pulling out from his bosses he asked me again " so whats for dinner?" I said babe im not thinking about food right now give me a minute " but I said it in a very aggravated way bc I'm thinking how is my husband... asking me about food literally while I'm crying and just found out..

He feels as if he has done nothing wrong but I feel as if he shouldn't have even brought up food especially 2 times with in 10 minutes of me finding out she passed away. On top of that as soon as we get home he has an attitude grabs a beer and goes to the bathroom and says " go get your book and tell me what bills are due "

I told him he was not being supportive that im already overly emotional being 27 weeks pregnant and not being able to go visit her in home hospice like all my family did.... he said well mabey you should find you a better husband since im so shitty.....

Am I over reacting... i feel like he is being a world class dick..... he never had the chance to know her like I did. You know the older people get the harder it is to know them bc they ramble on about lord knows what. He would hug her and say hey and she would start telling him about what's she fed her cat. Or what she did 3 years ago for Christmas. So it was hard for him to get that connection but for me its different that's my blood the one who gave me ice cream when dad said no. The one who would give me candy at church to keep me quiet the one who my daughter will never meet. It hurts. But am I over reacting to the fact that he's being so non chalant about it.
