You came from "sure you are wrong" to "maybe you are wrong".Maybe for some it is.
You're making progress.
I never seen the point to stay for years with a girl. I consider that I have truly be in love just one time. Like a mutual visceral need for the other one like food or water. All my relationhips were initiated because of sexual attraction, and in majority of the case because the girl shown signs of interests first. I was not always "mentally compatible" but I was happy because as long as there's sexual attraction, it can be fine. It's the vital minimum, a necessity, intelligence is not a necessity, but just a bonus.How many long-term romances have you been involved in in your life? How long have they lasted? What was the quality of the relationship?
And of course the guy was with you for your intelligence.:yim_rolling_on_the_especially if I hadn't actually experienced a long-term committed relationship myself.
