['In order try to get a friend to break up with her jerk boyfriend, I sent him fake texts that looked like they were from another woman.', 'Oh wow! Did it work?', "No, and it made her feel horrible because she thought that she wasn't enough for him.  In the end, it wasn't worth it."]
I bet you felt really bad. Did you end up telling her the truth?
A while back, my friend was fating this horrible guy, so I started sending fake texts to him from a throwaway number hoping she would see them.  I felt really bad about it in the long run.
