HELP! (concerned...)

Let me just say... WHAT A JERK!!!... tell your sis not to waste time on that guy.... but I guess right now what you can do is to spend lots of time with her out side of the house, eg to shopping, movies, hang with friends, whatever, just to keep her busy so she won't have time to think about that guy... and when she does think of him...try and talk her out of it... maybe that would help. :) Take care.
