What do you say about a person who does not know how to treat a nice person?

How in the world can you mistreat a good person who have major self-esteem issues and all they have ever done is be nice to you? Some people I know would say just walk away, but how do you do that when all you have ever been taught was how unimportant you are and that everyone on planet earth have a purpose but you. And when you find someone who say that they love you and then something goes wrong you are trying to fix it because in your mind since you have been groomed that everything is your fault than you think right away I must put this back together because this is another one of my terrible flaws. Your life mission is to make everyone better but yourself. When you think of a woman the average healthy minded man I would imagine look at a woman (especially when she is nice) as a gentle and kind loving soul that should be nurtured and treated like the special person that she has been created to be. But there are some real sickos out there that no matter how nice you are the worst they treat you. To think that a man would fix his mouth to call a any woman but especially a nice decent woman a mother ****** or a b***** a w**** and the list could go on and on whatever word at that moment that comes to his twisted mind he will say it and yes this woman is getting help for her low self esteem problems but he just keep throwing those daggers at her. It is so scary that some that are among us are so fragile and what is even more scarier is that we have people that are so cruel that they do not care or recognize that these people that they are doing this to have been so deeply wounded(in childhood) that they do not even have what it takes to fight these jack***** back! I hope if you are being abused physically or mentally that you get help and if you are the abuser you need to get help too because if you are so high and mighty then why do you have to make someone feel small to make you feel big? This woman have removed herself from this unhealthy situation but this Rocket Scientist continue to harass her, the best thing at this point I would think to do is pray that God gives her the strength to get a order of protection against the brut.
