Lots of good input. Generally speaking, do you INFx's even want a significant other? If you're like me - sometimes you do and sometimes you'd rather just be left to be alone. It's fun to be fairly independent - and obviously it comes natural to us introverts, but then there are times you really do want to be in a relationship with someone who is compatible (key word).
Does whether or not you want to be in a relationship change depending upon the circumstances in your life? Or would you say that generally you couldn't care less if you were in a long-term relationship?
