Excerpt from The Four Agreements

If someone is not treating you with love and respect, it is a gift if they walk away from you.  If that person doesn't walk away, you will surely endure many years of suffering with him or her.  Walking away may hurt for awhile, but your heart will eventually heal.  Then you can choose what you really want.  You will find you do not need to trust others as much as you need to trust yourself to make the right choices.
