We are always creating desire, and within our unconscious mind the super conscious mind is at work creating, thus the outcome of what we desire is already here... the person who is hurtful we created... by what we feel deep down inside.
Acceptance is key, we first must accept what we have created as ours... and also forgive that person because they are only part of the self. We have created everything because all matter and all quantum particles are in flux... and thus those thoughts echo throughout the Universe and echo back to us as Karma.
So how can we react badly to someone who is causing us pain, see them for who they really are... a part of the self... and love them even more.
Remember their heart is full of pain... and thus... we must have compassion and this means we must have compassion for the self.
And remember be grateful for the learning lessons they bring you... they are your teacher.
