The hardest part is that it requires us to accept that the offending party is never going to apologize, never going to see himself or herself objectively, never going to listen to our feelings with the slightest openness of mind or heart. Letting go of anger and hate requires us to give up the hope for a different past, along with the hope of a fantasized future. What we gain is a life more in the present, where we are not mired in prolonged anger and resentment that doesn’t serve us.
