Since your h is still living under the same roof with you, I would suggest that you talk to your h about it. You could say something like this: "h, I am planning to do xyz and would like to know if you are interested in going w/us. If you can let me know by xyz, because I want to purchase the tickets." You will have given him the option to say yes or no.
It doesn't matter what you say or do, he's going to be angry. Right now, he's angry at the world and himself.
Invite him, but keep your expectations at zero.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
