cigarette smoking is an addiction. the dream may be cluing you in to the idea
that the 'man of your dreams' is working on some personal problem that's
become a (seeming) part of his nature. it could be an invitation for you to
expand your 'applicant pool', and accept that "mr right" could be a 'diamond
in the rough' type. i don't see anything indicating that you'll need to help this
mystery man overcome his challenge... maybe just encouragement, or acceptance.
