All 3 for me. Wouldn't want anything to do with anyone falling into any of those categories. Been there, done that, bought the T shirt. Never again.
Life's hard enough anyway, and life throws curveballs. Fair enough if an otherwise "good" partner ends up losing his job, or becomes disabled and can't drive, but I'd not start off a relationship with that kind of "issue" already in place.
Maybe if someone was unemployed, but it was only very temporary one off and there was genuine likelihood of getting another half-decent job in the very near future, I'd dip my toe in and wait to see how it pans out, but I'd not be going into any commitment until secure long term employment was in place.
I suppose, similar with regards to driving, again, dip my toe in if they were having lessons, got the test booked, and had genuine plans to buy a car, then again, I'd bide my time and only commit once passed and car bought.
Bad teeth is fixable and simply no excuse, not for letting their teeth get into a bad way, usually by lack of care, and not for getting them fixed. A definitely deal breaker, not even dipping my toe in there.
As I say, been there, done that re a non driver and unemployed. Makes life and relationship a lot harder and more stressful and not worth it, as I was the poor sod who ended up being the chauffer and ending up paying for everything! Never again. As I say, fair enough if life throws a curve ball at you, but there's simply no need to go there from the outset. Easy enough to choose someone else or simply not bother.
