Oddly, we've had this question a couple of times before. People with bad breath or other body odours usually don't notice it, because any small that is around you steadily, your nose stops recognizing. ( When I visited the thermal area at Rotorua in New Zealand, for instance, when you first arrive you wonder how people can bear to live in a town with such a strong smell of sulphur ; but after 10 minutes you no longer notice the odour ).
In the situation you describe, I don't see much alternative but to discuss it with him, kindly and gently. Say that you care about him very much, but that he has really very bad breath and you're sure he can't notice it himself. Emphasize that you want to help him to solve this problem, because you don't want to break up with him. A dentist or Gp might be able to advise, as one needs to check the cause. Scrupulous tooth-brushing at least a couple of times a day, scraping the tongue if it's furry, and using mouth-wash is likely to help. Sometimes bad breath can relate to other medical conditions, and thus a medical check-up is indicated if the obvious remedies don't work well enough, as the odour may indicate somethig more is wrong, and needs to be helped
