I've been dating this woman, Betty, pretty lightly for about a month. Can't say we've had any really deep conversations, but it's been going well. The other day I shared that I'm training for my first marathon and talked about my training plan for all of about 30 seconds (because I know 99% of women don't care about this sort of thing), and Betty immediately started telling me I was doing things wrong and that I should do X, Y, Z instead (all of which made no sense at all to anyone who knows anything about running). She didn't rant or anything, but it was still a pretty giant turn off for me as I was a national caliber runner in HS and college and am still very fit, and she doesn't run at all and knows nothing about the sport, training or otherwise. Might seem kind of trivial, but if someone's impulsive reaction is to think they know more about something despite having no knowledge or experience with it than someone who has actually lived it for 15+ years, I see it as a pretty bad indication of their broader personality and what may come down the road. It's also a bit of pet peeve of mine, so I might be overreacting... I just don't understand why people act like this. I've never argued with an electrical engineer about engineering because I have no knowledge of or experience with electrical engineering. It seems patently obvious to me that arguing in a case like that would be an extremely rapid way to make a fool of myself... But that's just me.
What do you guys think? Dealbreaker? Or no?
