I totally get this. I married and ex smoker. I have to make sure I don't smell like smoke before going to bed so he can sleep. UGH I am so happy my hair doesn't smell like smoke and I don't have to make him wait for me every place we go to smoke.
I married a man who's never had a drag off a cigarette or anything in his whole life. (He's so clean he gets drunk on half a glass of wine LOL) He's never really cared if I smoke or not (didn't even bring it up when I got pregnant) I never knew what to think about this: on the one hand I like that he doesn't ever nag me or make me feel bad or dirty
