Understand people's motivation
Most people who appear to take some pleasure in hurting you have some pain in their own lives. Most feel justified in what they are doing; otherwise, they would do something else.
Whatever this person has done, look for some explanation of their motivation. These are not excuses, just explanations. Before you forgive someone, it helps to understand the reason for their actions.
"And in the end, the love you take, is equal to the love you make…" ~ The Beatles
