I'm so sorry for your lose, and for the future that is now gone.
We often do not, or can not, see what is coming ahead..we can only deal with what is left behind.
Peace unto you, as you suffer..and peace be upon those he left behind.
I've been in your spot, and closer to the event. Be hopeful that you can help his family with your obvious love for him.
Never give up hope..guide as well as you can.
And again, Peace.
