Borderline Recluse????? Tal that is NOT a recognized psychiatric diagnosis!
The closest thing I can think of is Schizoid personality disorder...in this one, the person just doesn't get anything out of social relationships...they tend to be life-long loners by choice. Only rarely do they form long term relationships.
They tend to choose solitary jobs, and are really deficient in emotional responses, good and bad, in social situations. It's the diagnosis the Unabomber got!
