Dear Paradoxy

She had told me not to tell my only other close friend that we broke up,

She made a demand to you, that you legitimately chose not to comply with. You were not lying, but the opposite you spoke the truth to your close friend.  If a bully told you to jump of a bridge, would you beat yourself up for not complying?

Finding good healthy truths in your life are important, they will help protect you from being coerced & manipulated in future situations.
