Daphne, my wife went through a marriage that was emotionally and mentally abusive (but “He never hits you, right? So it’s okay?”) from the honeymoon on, for almost five years. She finally walked away. He didn’t put up a fight, although she’s pretty sure that was only because he was convinced she’d realize she had made a mistake and would come crawling back.
So it does it better. No guarantees, but that’s the way to bet.
