Hi CanBird, well, the last dating book I read "How Not To Die Alone" strongly encourages at least second dates unless there are red flags and putting off "Is he the love of my life?" and rather answering "Would I enjoy another date?" It's by someone who worked at Bumble and I guess they feel we are often bombarded with too many options when dating and we often make snap judgments on criteria like 5'8" vs 5'9" or how photogenic they are.
Is smoking a dealbreaker for you? If yes, I wouldn't date him.
I've only dated non-smokers before. I admit reading about Bach #2 is making me re-think that stance. It seems similar to a known health condition like "family history of cancer". I'd be more worried if I saw myself introducing them to my children since he'd be modeling a bad habit that could dramatically shorten their lives.
