I'm curious if your personal experience supports this or not. Below is a poll. If you are monogamous, please answer this based either on your current partner or if you are single, on your last relationship. If you are poly, please answer based on your primary partner.
Let's put this to the test!
You and your partner have similarities in background
You and your partner have a similar temperament
You and your partner have similar goals and dreams
You and your partner have similar values
You and your partner manage and order your physical and mental lives in similar or compatible ways
How long have you and your partner been together? Or if you answered the questions based on your last partner, how long were you together?
