Facebook Stalking

How do you deal with it???

There is an individual on Facebook that has been stalking me. Up until last week, I've been able to just ignore it. But this person has taken it up a notch. He/She is looking up things I wrote almost a year ago. He/She is commenting on everything, not missing a single "like". It's to the point that I feel like he/she is monitoring EVERYTHING I do. I do not mind people commenting and liking my posts, but I think it's gone too far. No one can possibly like everything I post. I feel like this person clicks like just to make sure he/she is not missing a single comment. In addition, this person is befriending unsuspecting friends and family of mine that do not know her at all. Some have already fallen into the trap.

Earlier this week, I tried blocking this person. Like fly on poop, this person was right on top of it, sending me a message asking what he/she had done, and that he/she thought we were still friends. What could I do? I told this person that I had inadvertently blocked him/her (which actually did happen to one of my friends).

This person is very positive and supportive in his/her comments, but EVERY COMMENT AND LIKE??? And I do want to continue a friendship with this person outside of facebook. I am worried about what might happen if I confront this person, as he/she has a history of being emotionally needy, and perhaps unstable. But, it may come down to confronting this person. Any suggestions?
