I haven't ever smoked, but my mrs did when I met her (roll ups, plenty a day for about 16 years). Wanted to stop but her husband also smoked and was a right jobby, all her friends did and she worked with some really jobby people at work so she didn't feel able to (need for an escape etc.)
I never pushed it on her at all, but not long after getting with me she decided to stop. She went cold turkey on the Boots thing where you get free patches but have to go in every week to blow into their crafty cig detector machine to see if you're behaving or not (that kind of 'target driven' thing works for her).
She was on that for about 8 weeks I think and that was it, 2 years ago now. Very impressed with my lady for achieving it first time out
