I know quite a few NTs, and the world feels that way to them too. They have an easier time forming relationships, but their relationships never seem to be very meaningful. Me, I've been in relationships ranging from 1-night stands to an 11-year marriage, and I now have ZERO interest in any future relationships. None. Every day I am thankful that I get to work at home and avoid people.
Having said that, though, I needed that experience with people to arrive at my current state of contentment. I remember all those years looking at the people around me and thinking I was missing out on something. Ho ho ho. What a difference a little perspective makes. Unfortunately, though, others can only give you glimpses, which aren't enough, and which aren't even accurate, considering they have nothing to do with you. Your own experience is what will give you your own perspective, and (alas and alack) there isn't any shortcut. You have my sympathy, though.
