I think if you are able to realize that your actions are unhealthy and unfair to this other person you can find ways to stop your obsession..

When you feel the urge to snoop .. dont ! find something else to do, read a book , do some cardio exercise , call a friend ,goggle a topic of a place you one would like to go to one day.

Please delete your fake facebook page.. Its only going to give you more problems.

If your unable to stop this behavior please go to a professional for help.

Take care
