Hi @CFH
I'm so sorry to hear about the loss of your dad. Losing a loved one is never easy, even more so when the death was fast, unexpected or especially traumatic to witness. I'm hearing that its still quite fresh for you, which is so understandable, its not even been a year. grief is something that stays with you always, its just the way that you feel it and carry it that changes. It makes sense that its still so prominent in your life at the moment.
I'm also hearing that you're feeling quite unsupported by your spouse. I totally get your frustration and anger, anyone would be upset to hear those things from their life partner while grieving the loss of a parent, diagnosis or not. He sounds a bit selfish, worrying about himself while you're processing the loss of your dad. There's no timeline for grieving. While it is true that most people can expect to have to bury their parents, it doesn't make it any easier when that time does come.
I'm going to leave the resource for coping with grief for you, you might find it helpful.
Take extra gentle care.
