You'd be surprised at the number of ex intimates and children of people having this personalty ,end up taking psychology courses or philosophy. As you know that something ain't right but it has to have a name since there are so any repeating patterns of behavior. I found in a course of logic- insructore made a throwaway statement that turned the page for me. Many of us have a pseudo degree in armchair borderlinology. LoL. We had to do it, they weren't interesting in learning about themselves. The proble with this is that it simply forces us to stay to tell the all that we have learned about them. they have zero interest but they realize that you are spending EVEN MORE time with them... Meanwhile they are looking for another favorite person .... it's a fun game for them.
