I really want to help my wife quit smoking. Has anyone helped someone quit who isn't working hard themselves to quit?

She had said that after her hysterectomy in late Sept. that she was going to quit smoking. She hasn't changed any of her habbits regarding this.

Our history is that we both smoked when we met (though I had just re-started again) back 15 years ago. Married 11 years now, she's still at it. I had quit in Dec. 1999 and it's been a good experience. I'm on a living healthy kick (it's more than that) since early this year and have lost 40 pounds, dropped 5" on my waste, walk 3 miles most mornings with the dog, eat better, knocked down my cholesterol a bunch and feel like I am 20 years old again (I'm 41).

My intention is to help her live longer - and better - for the next few decades. Her life is limited but is opening up now that the pain of her problematic repro-organs are gone. She's "considering" doing the morning walks with me and she seems to want to eat better. Still has various issues with pain, nausea and similar issues to what she had before the operation.

Her next operation she wants to do is to lower the pain in her upper back and neck - through a breast reduction. She's lost 60 pounds since our 2nd child was born but her breasts didn't make it through the process too well and now she says she has multi-years of bad pain in her neck and back (mentions cervical dystonia).

Is this me just saying "I want a healthy wife!!!!"? Am I selfish in doing so? Is it bad to want more than they have in terms of your partner's health and outlook? Also, my wife also says she'll never stop wanting more out of the people in her life - such as me.

What doesn't help this matter is that my adoptive father died when I was 6 yo due to effects of smoking. I want my wife to make it to her 60th birthday (20 years from now) in a healthy state.

Has anyone worked to help someone really reach their physical potential while pushing aside the main issues they stay in the rut they are in pertaining to the mental health issues that keep them doing old habbits?

She's gone through therapy a couple years ago and says "she's already worked on the big issues of her life".
