Betrayal according to Wikipedia is the "breaking or violation of a presumptive contact, trust or confidence that produces moral and psychological conflict within a relationship amongst individuals, between organizations or between individuals and organizations."
As humans when we are betrayed by that one person that we trusted, loved, cared for and kept close to our hearts, it causes a kind of pain that is not easily healed.
We tend to feel useless for allowing that person get that close. It brings down our self-esteem and we wonder how we could not read the signs or know the person was capable of such an act.
There are particular ways to handle such betrayal if we intend to recover from it.
GET AWAY FROM THE PERSON
The first step is distance. You need to distance yourself from the person that has caused you the pain. Constantly seeing and talking to the person would only remind you of the betrayal and would not heal you.
UNDERSTAND IT TAKES TIME TO HEAL
I would not come here and tell you that you would get over the hurt quickly or in a few days because that won’t happen trust me. It would take time. Sometimes months and during that time, oh, it would hurt so badly. But this is where you need to understand that it is going to take time.
EXPRESS YOUR EMOTIONS AND FEELINGS
Keeping how you feel inside would not help anything. You would need to express your feelings. If you need to cry out your emotions do it. Write down your feelings if you have to.
TALK TO SOMEONE YOU TRUST
Go ahead and talk to someone you trust. Talk to someone that would certainly listen to you.
GET A LIFE
Yes, I said it! Get a life. Sitting around doing nothing and just thinking about what you are going through would not help in anyway. All it would do is cause you to grief more. Go out with friends, focus on your job or get a new hobby. These things would keep you busy and leave you with little time to think about the pain.
TAKE CARE OF YOURSELF
Understand that you matter the most. So make sure you take care of yourself.
