I've been with my partner a few years now. His breath is vile 90% of the time and I mean vile, not just up close either. I've spoken to him numerous times. I've tried to be kind and sensitive. He always seems a bit hurt. He has good oral hygiene. Brushes, flosses, scrapes tongue, regularly visits the dentist. Nothing seems to help. I'm so put off by it that I'm going off him. I actually recoil at times. Any advice?
