Forgiveness means different things to people. In a psychological sense, it's about overcoming negative emotions like resentment and a desire for revenge so in this context it's not about forgiving someone for something they have done, it's about freeing oneself of these negative emotions.
Forgiveness in relation to forgiving someone for what they have done is in my experience much harder, especially if that person hasn't sought forgiveness.
Several years ago I heard an Archbishop (can't remember his name) talking about forgiveness and he said that to be forgiven
you need the three R's; remorse, repentance and restitution. So unless it is asked for, the act of forgiveness may help the one doing the forgiving to free themselves from negative emotions, but makes no difference to the person who has done them wrong.
I agree with what you say about separating abuse into too many offshoots as childhood abuse takes many forms. The majority of parents I'm sure, who take the decision to send their child to boarding school believe it's in the best interests of their child, so it's not done as an act of abuse.
