Anyone else hiding that u smoke from your s/o?

I know this sounds kinda bad, but my boyfriend always told me that he finds girls that smoke “unattractive” and that if I ever started to that he’d break up with me. I used to do it rarely, but lately I’ve been smoking everyday and he doesn’t know. I like to smoke, but I want to quit soon because it makes me guilty..it’s funny though cause his friends smoke and he knows my dad and brothers smoke and he isn’t against it with them. Just with me 😂 what’s your guys opinion on this?
