You did not do anything wrong, you were simply being a nice and caring person. When someone goes to such great lengths like you have described they are VERY lonely. While it's very much on the creepy side, I suggest you think of this as that you were "nice" and caring to someone who must have needed it REALLY BADLY.

Yes, some people have such low self esteem that they create an identity that is totally fictional, not anything resembling who they really are IRL. It's actually "sad" that someone would need attention that badly.
