How do you stop Caring about people

I want to know how to emotionally build a wall?

There are so many people who are smiling and nice social and they actually don't give a dam about people about a person that they are friends with family with

There's men who they say everything you want to hear and they date are in a relationship say I love you and they actually have a wall and they don't care about the women they love

It's like the story of a wolf that was apart of a group of sheep and they thought he was a sheep and slowly started to eat the sheep.

How do you protect yourself from these people I don't know whether to call them intelligent or lying or traitors betrayers pretenders but it's like they have the ability to trick people it's like a political thing where people say I love you and they smile put on a face reality they don't care about. It's like those friends that when things get tough they leave the Fair Weather people when it's nice they are there when you need help or you have problems they walk away
