Relationships Make You Feel Good About Yourself

Part of the reason breakups are so painful is not only the loss of companionship but also the sting of rejection. This thought of "I am not good enough" "I must have done something wrong" etc. This is amplified if the other person leaves you for somebody else. Then you are faced with "why them and not me?" Especially if they are, in your opinion, not as good as you are. So in other words - it is our own selfish egos feeding you grief and misery compiled on top of the loss of friendship.
