I can tell you that in high school and college, I was both dumped and did the dumping when my value set/lifestyle/background was too different from my own. I’ve broken up with people because their value system and “what is normal” was too different than my own, and it caused problems eventually, no matter how I felt about the person or they felt about be. There was always a sense of imbalance. I went through periods where I tried being things I’m not—political, overly social, interested in athletics, religious—and it never really worked. When I felt false, the relationships where those interests were a basis of commonality felt false.
The reality is that I’m a very moderate person, and I’m attracted to people who are doers. I don’t well with partiers or who are into material possessions or pretentious. I’m attracted to people who are curious and who like to tinker with things, make things with their hands, entrepreneurs. I like people who notice things.
