I think it is a big stupid mistake for a woman to go back to an abusive relationship. Nobody has to tolerate such behavior from anybody.
You were handed a red flag. Don't ignore it
No I wouldn't. It isn't a mistake. It is mistreatment. and leads to misery. My sister was hit by her boyfriend when she was 16. She told him she wouldn't date him any longer. He was forever sad but she couldn't chance abuse. Love is much better and hitting is not love.
A Mister meaner perhaps?
