A narcissist can dish it out but he cant take it in. He is very intuitive and manipulative and he knows exactly what to do and say to make you love him. It's not so bad for girls who just want a handsome guy to make her feel special because once he doesnt make her feel special anymore, she will just find another. but to a woman who really loves and cares, he will pull at her heart strings and make her want to help and comfort him and don't give up by telling her how messed up he is and looking to her for love and acceptance. Once he has her devotion and care for him locked in tight with emotional attachment. Then he begins the abuse. She stays because she believes that he needs love and patience and forgiveness, someone to look part his bad behaviour and believe that he is not all bad and he can change. He feeds on her emotions while abusing her. But if someone could hurt him like that, he wouldn't be able to take it for a moment. He could never display the strength and endurance that his victims display.
