Had a much needed talk with G on the weekend. The most important sentences we exchanged were:
Me: "I can't really imagine us as a couple. Can you?"
G: "No, not really."
We discussed reasons why, and one that G gave was that he felt intimidated by my intellect.
Sigh - it can indeed be lonely sometimes at my end of the bell curve.
I like to think though that intellect is as much an attitude as a question of brute mental capabilities. Intellect is a certain curiosity about the world, a pondering of why rather than just what, an ability to ask a question when you don't know something rather than being afraid of your own ignorance.
Perhaps intellect is a personality type as well - I think so, and I think that's mostly why it would probably never work with G.
