Best friend is someone who can be trusted and who can be counted on. Best friend should be always behind us regardless under what circumstance. They should support us no matter what. They are the one who keeps our top secret safely but, when they intend to speak it out to other people, that is what we call as BETRAY. Best friend can sometime ruin us and give us a bad time. They might have intention to betray us for their own good.
Neglect them
When you are under circumstance where your best friend tend to betray you, all you need to do is just leave them behind. Do you things by your own without asking help from them any longer. Stop counting on them. Show to them that they are no longer indispensable and you can do everything by your own without their presence.
Do not trust friend more than family
I would advise you,regardless how kind your friends towards you,do not put you 100% trust to them. They can simply take advantage on you as they have your trust. It is better to put your trust on your family for instance, your cousins, sibling etc. From my point of view, they will be more immortal than your friends.
Find a new best friend
Once you have found out that your friend betray you, without second thought, go and look for a new friends. Do not wasting your time to get upset and dwell about what they have done to you either it is good for you or backfire. They are good for nothing.
Do not stick to only one click
You shouldn't get along with small amount of people. Make friends with everybody. They will be needed if something bad crop up between you and your best friend
