^ You come off as being excessively judgemental. Some people live fast and die hard. I could make arguments for and against that lifestyle but ultimately it is the choice of the individual.
I wonder though, are you judging her too harshly because she just didn't reciprocate interest when you assume she would, because you assumed she was at a lower mental state because she smoked?
You obviously don't have a high mental state if you can't stick to facts like embellishing "one honestly can smell her from about 20 feet away".
Intelligent people seek accuracy and truth. Granted, she wasn't all that intelligent either if being a model meant smoking excessively to curb food cravings, and it's hard to imagine even smoking 4 packs a day, that is more like someone who always has a cigarette burning but isn't actively smoking it. This happens. People start smoking fewer cigarettes but inhale more of each one instead of having them burning as if they're incense.
At any rate, you don't need to know how to respond to it. A generic "good" is better than being socially offensive. You can't change someone's behavior by trying to shame them, it will onlyl make you one of those stressful people that are a trigger for more smoking.
I'm just calling it like I see it, that this woman was not right for you, different life choices, different attitude about life, pick someone who shares the same values... been there, more times than I can count.
One thing though, you are not obligated to socialize with stinky people (lol). If you are happier somewhere else, be somewhere else.
