If somebody you knew like a family member, partner or friend told you they had NPD would you still talk to them? Would it change how you feel about that person?

As someone with NPD I'm always worried about how having NPD would affect me socially. It's so stigmatised and people are always talking about how dangerous people with cluster B personality disorders are. I'm dating this guy at the minute. I really love him but I'm worried about how he would feel if he found out about my NPD. Would he still want to see me after what you see online about NPD? Should I ever tell him? Should I just keep it secret?

As of now I've told nobody about my diagnosis other than a few people at job interviews. What I'm basically asking here is 'How will NPD affect your social life?'.
