If she is a really addicted like my wife was, your in for a long hard road. If your tactic is its me or the cigs, no one likes an ultimatum. If she doesn't smoke around you it just means she smokes more when she is not with you. A friend of mines wife use to smoke half a pack on her way home from work because she couldn't smoke around him.If she is willing to try and quit get her to do this-

Stop cold turkey for three days- no cigs,drugs,sugar,caffine but take lots of vitamins c/ b complex/d

On fourth day have her sit in front of a mirror with a bright light shinning on her face, then she needs to chain smoke any nasty brand cig,not her own brand, not stopping, every breath taking a drag, usually will puke after the 2 or 3 cig, but don't stop until they do and feel like hell, the reason for the mirror is to see the physical effects of smoking on your body once you have detoxed from nicotine.

Hope this helps you, I know where you are at.
