Manipulation :- Exercising unscrupulous control or influence over a person or a situation. . . Characterized people by their action, Trust me you will never get fooled by their words. And trust me if one's action is affecting you and your self growth, and that person can't see any issues by that....you need to move out of such manipulative relationship.
Learn to look past the criticisms. Hold them in your heart and let the words drift by after absorbing every word of theirs. Sugar coated words are pretty satisfactory but, they stagnate you in the run of life. But, it works as long as you find the balance between hate and love, where words are just words and sometimes not the parts and pieces of the soul.
