People who don't like intimacy? schizoid?

Link A NY Times article about a psychotherapist who met a severely introverted man who attempted suicide after being pressured to have a girlfriend by his parents at the age of 35. The doctor believed the man just didn't take well to dealing with people. I can sort of empathize -- I mean people can be trouble, but dealing with them is at least interesting, at best fun and at worst frustrating, still nothing worth doing oneself in over. But I digress, the psychotherapist basically disputes the widely held idea that one should force such people to conform to norms by being more "normally" social. He said what was best for this guy was just to leave him be. Seems sensible to me. Plus, maybe the guy was gay.
