Unfortunately, there is no feasible way to know if your boyfriend has paranoid personality disorder (PDD). You’ve included a list of the symptoms as well as a description of the disorder but nothing you’ve written leads me to believe that he has PDD. This is not to say that he does not have it but I can’t tell if he does from your letter.
I also want to add that I find your relationship to be somewhat unusual. You wrote that you’ve known each other for 11 years but you don’t know his last name, the schools he attended, and other basic personal information. You practically know nothing about him. Additionally, it’s not clear in your letter but it seems as though you’ve never met in person. I’m not sure I understand how you could carry on this relationship for so long with a virtual stranger.
I would caution anyone from dating an individual who would withhold basic information about themselves. When it comes to the Internet, I can understand not sharing personal information in the first few days of interacting online. You’d want to get to know someone a little better before you’d share personal information with them. That I understand and I think it’s smart. According to your letter, however, you’ve known this individual for 11 years and you know very little about him. It’s odd that he has not provided you basic personal information but what’s even more peculiar is that you’ve stayed in this relationship for 11 years with a person you barely know and have never met.
I’d suggest before you continue this relationship you find out who this person is. What is his last name? Why will he not share basic information about himself with you after 11 years? It also would have been interesting to know how often you and he communicated or if the two of you have ever spoken on the phone. Do you know where he lives? Perhaps you’re dating a convicted felon who is contacting you from prison. Perhaps not but it is a possibility, unless you have evidence otherwise.
If he’s not willing to reveal basic information about himself at this point then it’s reasonable to conclude he never will. If that’s the case I think you need to reevaluate your relationship with this person and make it a point to only involve yourself with individuals willing to share more than just their first name.
