Andrichik, does he have paranoid ideas about other people and topics too, or just about you? Whether or not he has this disorder, I'm worried about you being in a controlling relaitonship like that. Would he be willing to go to counseling? How about you? Individual counseling for either or both of you, and/or relationship counseling would probably be invaluable, whatever you two ultimately decide to do with your relationship.

You should not have to be scared to talk to people or go out in public. Isolationary tactics always concern me, regardless of what disorder may motivate them.

All the best to you!
