alicesister, try deflection. When your husband starts to get upset, take him to a window and ask if he saw the coyote that just ran through the yard (for example). Any rapid change to another subject that causes him to pause in his thinking might help.

My husband is same,he lives in the moment,I try not to mention stuff in front of him unless I have to,so sad for them,when his kids call or come he forgets a hour after then gets depressed because he thinks they never come or call, what can we do just do our best ,I have learned to know some things have no answer ,just patience mercy of God to guide every day

I agree
