I'm going to refuse sex with my husband because he has stank breath
Oh no that is terrible. How do you feel when he breathes on you?
I felt really angry and I may punch him because of it.
Having smelly breath is no reason to want to physically harm someone. If it really bothers you, I think you can just simply ask him to brush his teeth.
It's so annoying. I'm going to hit him with my vase.
Violence is never the answer. It is not okay to refuse your spouse sexual pleasure because of something you dislike about them. Maybe you can buy them a special toothpaste or mouthwash to help with the problem.
