Would it be acceptable to you —at least as a first step—for him to just not smoke around you? I don’t think it’s wise to believe you can make someone change something like that. It has to come from him and I don’t think it is an easy thing at all, regardless of your age. I don’t have as big a problem with smoking as you do, but it is a huge turn-off to me, so men I date who smoke know they can’t smoke around me. If we’re outside and they can go a little farther away, fine, but they certainly can’t smoke inside with me, where I will ahve the smell on my clothes, etc. and if we’re going to kiss or anything, they better have gum because it tastes awful! Lol. Anyway, it’s important not to ignore your feelings and to make sure they are known and respected, but you also can’t change someone nor can you expect them to make that big a change JUST because you want them to, especially in the context of such a short relationship thus far.
