>>2 here.
I've only ever had a relationship with someone like that once however she was a child and not a very bright one either. I would sometimes tell her things and then she'd run around telling everybody else. She can't keep a secret. She also had a crush on me but I didn't feel the same way so we drifted apart over time, I felt bad about that.
I do have friends, although we've never really met in real life.
