Trying to cushion the blow by dancing around the issue just makes things worse, says Miami Marriage and Family Therapist Lisa Paz, Ph.D. “You’re about to shatter someone’s world, so rip the bandage off fast,” says Paz. “Tell him, 'I made a mistake. I am terribly sorry.'" And don't keep the possibility open that you might change your mind. You’ll only break his heart all over again.
