It's probably more instinct related but I'm wondering if anyone has noticed any patterns in terms of some types needing/wanting to be in a relationship whereas others being more okay with being alone. Could also be an introvert/extrovert thing. I read somewhere that extroverts tend to get married before introverts and when they marry each other (E-E relationships) it goes south eventually. I wonder if that's true. I don't remember where I heard that now.
