I dated someone who was closet cray - cray. Some next level craze..
After I GTFO, first came the death threats, followed by some stalking, which finally evolved to being called every name in the book to anyone who would listen to him - for 7 years.
At least he didn't boil my rabbit. I lost a lot of friends due to the name calling but I don't care. It was worth it just to be free.
