I don't understand what situation you could be in where he would smoke around you? All public places are non-smoking, so if he is smoking around you then I would assume you are choosing to be in a smoking area? If he smokes in your home then I think it's simple, ask him not to! It's your home afterall, and even though my husband smokes and I did until last year, we have never smoked indoors because it stinks. Lastly, if he is smoking around you at his own home then I would suggest that you ask if he minds if you open the window as it makes your asthma play up.
I guess it's down to personal choice as to whether the taste of a smoker repulses you or not, it doesn't bother me, but it obviously does with some people.
