Confused...one thing...don't nag about it

My hubby smokes cigars and sometimes cigarettes. The cigars I don't mind, but cigarettes drive my asthma mad. Since we started living together, I haven't said a word to him about it, except for one time he kissed me right after smoking cigarettes and I told him to go brush, LOL.
My not saying anything though, has actually worked for me, because he knows how I feel about cigarette smoking, and he has smoked less than a full pack since being here for the past 5 months! In time, I know he will give up the habit all on his own, and the only thing I needed to do was be patient and supportive.
