Depending on how crazy, there's no gettin rid of her. When my ex tried to get rid of his crazy, she hacked in to his email and started emailing me pretending to be him breaking up with me, then hacked in to his Facebook and took us out of a relationship.
Funniest part: he knew shed hacked in before she did any of that, so we were on the phone laughing about the whole thing as she was doing it, playing along. Lolol
