There are always trade offs in life.. On the dating front at least. If I spent more time in general hanging out and out and about on weekends goofing around like many folks I'm sure things would work out differently. One has to consider that for me often I'm left to just generally low stakes / OkC derived meet ups.
Statistically speaking at this point I can say that coming across as passionate about ones life's work and mentioning that entails a day job at times and often night / weekend effort doesn't set the tone of being emotionally or otherwise available even though that may not be the case nonetheless it is best to can it on the first meetup... That is all.. It's bad enough being an introvert in an extrovert's world.. :)
You may find someone special who really digs what you do, but you can only ignore them and keep them at arm's length for so long before they leave to find someone (perhaps less romantic) who will treat them as if /they/ were that important.
Certainly there are exceptions (mariner's wives come to mind) but I think this would be true of your normal random date. So, romantic? Sure. But the appeal has to eventually wear off and then there'd better be a part of you that you can devote to your partner.
