Why do I attract the stalker-type?

Honestly, I've had 3 guys want me SOOO badly that it has scared me. It's not JUST intuition they've said it themselves. Like I'm not just saying this to "affirm my own brilliance" or blah blah blah. But it makes me wonder why?? Seriously.. what is it about one person that makes another person infatuated with them? Any insight?
