Based on the responses here I’d say the designer personality is generally that of a jerk 
C’mon guys, no reason to be so hard on the OP.
I think you will find that many (not all) designers are a bit OCD with a high attention to detail and the ability to nerd out on their work very deeply. Are these unique traits to designers? Of course not, but they are hard to live with. My recommendation is to find someone who finds those qualities endearing and supports your creative habits. Good designers don’t tend to be totally ‘normal’, whatever that even is. Find someone who respects you for who you are, shares similar interests, and has complimentary skill sets.
And if you are a very ‘normal’ designer who likes sport ball, doesn’t care if the place is kept up, doesn’t have a taste for the most exotic coffee or rare bourbon, and doesn’t have whiplash anytime a rare car drives by… consider yourself lucky. You can relate to more people and empathize with more end users.
