Is forgiving someone who doesn't regret beneficial for you?
Forgiveness is a way of soothing oneself and finding closure.
The benefit of forgiveness has to do with the relief coming from the fact of accepting the past, which entails forgiving yourself for not preventing the hurtful situation - thus eliminating the shame and some of the hurt.
The underlying feelings like hurt or shame are not resolved, but rather subdued.
