I know, I'm messing in your business. Mine, too. But first, I would like to say what I mean by forgiveness. To me, that doesn't mean remaining a victim. You can stand up for yourself and still forgive who hurt you. The consequences of their actions will only change because you will not remain impaired or injured by them, but the incident can make you more empathetic and actually stronger.
Their negative consequences of being a jerk or bully or worse will continue. To me, forgiveness doesn't even mean no legal action, or never speaking to them again, or throwing their stuff outside on the front lawn. That might be the right thing, the fair or safe, or just thing to do. To me, forgiveness means you believe you aren't in charge of the consequences this person deserves. A person of faith would think God is keeping track. Just by logic, a jerk, or bully, or criminal will have consequences sooner or later.
You are just not in charge of the ones that don't affect you directly. No revenge. No taking up your thought life with what you'd like to happen to them. That is not healthy--that sucks up your energy and good plans for the future. It robs you of the joy of the present.
To be honest, this is my hardest Jesus Instruction. The Lord's Prayer--forgive us our trespasses as we forgive those who trepass against us. Arggh. Real clear. Takes humility to admit we aren't perfect and need forgiveness, and grace to forgive others, and faith to let God handle it..
Look out for you and your future. Don't let that ugly occurrence put you in prison--emotional or otherwise.
These are all non-religious sources concerning the psychological benefits of forgiveness.
