You are (with the best intentions) overloading your H who is NOT receptive to these actions/words at this time.
DO NOT say ILY...just stop it...can you not tell that he is only reluctantly returning this phrase? How do you suppose that makes him feel?
I'll bet he feels CONTROLLED...like he has to respond in kind or there will be some sort of hell to pay...ditto with the expected phone calls.
He seems to be telling you quite clearly that he needs space right now...he sounds stressed from work, pushed into "knowing what he wants" while driving home.
Pressure....that's NOT what you want to create for him, is it?
Someone else put it well: HAVE the meal there...if he's not hungry fine, no problem. Let him unwind some, hold off on suggestions, drop this rope for a bit...see what happens.
