As I read your list of examples I was self reflecting and thought something to myself and then found my thoughts rith there in your post -
"I am sitting there, facing him, looking at his face and he will not complete his sentences. Just like kids do when they are afraid what they are saying may turn out the wrong thing."
I am 46 and still act in some ways like a kid. Some things don't change. I would say he is afraid to finish the sentence because he either lacks confindence in his answer, is afraid to disappoint you, or will anger you with it.
If this is the case only you can help answer which one is the right one. I would say be careful answering his open ended statements. Only he knows what comes next and if he is afraid or trying to avoid conflict it is very likely he will agree with your answer even when you are wrong. This allows you to walk away with the wrong impression or feelings.
You could try something else. I had a mentor once who would ask a question. After you gave an answer he would just remain quite and look at you - as if waiting for the rest of what you had to say. The period of silence is vey un-nerving and you start to feel compelled to talk more. Then he would still remain quiet just nodding his head ... and you try to add more because you felt the urge to provide more. He was a master at this and it really worked. Took me a year to figure out what he was doing and that it was intentional
Reflecting on myself it sounds like your husband is just trying hard not to offend or trying not to do somehting that will push you out the door...which actually a round about way of trying to please you... I guess it depends on your perspective.
