I'm not suggesting for one minute that you have bad breath, body odour or smelly feet for example, but if you did, would he say something? If he is inclined to point things out if he finds something about you annoying/repulsive, then he shouldn't get angry when you do the same. Does anyone else say anything to him about it? Do you have a family member who could point it out when near him?
My wife and I have an agreement that we tell each other if there's a bit of a wiff, as it's better that we say something and correct it, as opposed to other people cringing and commenting. Maybe you could suggest this as it would let him feel he could say something too, therefore feeling equal and included.
Assuming he cleans his teeth regularly, and doesn't eat food that will cause bad breath, there may well be a medical reason for it. Might be worth looking into.
