How can I stop someone from hurting me when they don't care about my feelings?

What I did was I took a stand and I said you know you were only hurting me because I let you. My feelings may mean nothing to you but it does not bother me any more I am my own person I don't care what you or you think if you don't like me them why do u hang around me. The closets you get to being perfect it being your self don't let anybody change. If your like me and are scared to say it don't let it get past your braking point. If you want them to listen you have to do what you have to do (I don't mean hurt them)

Try the best you can to remove yourself from situations where they can hurt you, stay strong and think of yourself

The first step is to stop allowing them to hurt you. The more you allow something is the more it will continue.

If someone truly doesn't care at all about your feelings, you really shouldn't be sharing your feelings with them. Separate yourself from them, or if you can't, don't talk to them about personal things that might hurt you.

An unfortunate situation :(. The trick is to be happy and in a state where your feelings are not possible to be hurt. Once you do that, you can handle the other person's pain as well, and help him/her through whatever it is that is causing him/her to cause the pain to you.

If you know they don't care about you, then remove value from what they have to say. Don't give their words any leverage over you. Once you realize that they are filled with venom, you can remove the effectiveness of their ammo. People only have power to hurt you of you give it to them

The only real way to stop someone like that is to avoid them as much as possible. If someone doesn't care about you, then there is nothing you can say to them to stop their hurtful behavior.

take yourself out of the abusive relationship! drown them out. You are better than to let someone walk all over your emotions!

you just cant..you will try to run away from him/her..,may be find another to distract yourself from him ..may be block him but he will stay in your head...but you can keep yourself busy and healthy ..with help of good diet,exercise,sleep,meditation,hobby ..be socialize and extrovert ..hang out with friends .Only time can heal your pain of onesided affection,attachment and love.

Don't let get close enough to you to hurt your feelings, if they don't care about you I see no reason why you should put yourself in harms way trying to care for them.
