Husband gets offended and mad

Hey ladies. My husband has HORRIBLE breath. Its so bad that it is uncomfortable and i hold my breath to kiss him. Its chronic. Ive tried as nicely as possible to explain this to him but he takes offence. There are times he uses mouthwash instead of brushing and will only brush his teeth once a day... if that. Mouthwash fades and its back. He drinks so much coffee and never brushes his teeth. I dont want him to feel rejected and i dont want him to feel offended. I just want him to understand im saying it because i love him and i dont want to be constantly dreading sex and kisses because of his breath. He refuses to do anything about it and gets mad and victimizes and gaslights me every time i try and tell him. I try to be so nice about it but nothing changes. What do i do? Its a serious problem for me.
