If someone repents you should be merciful and forgive.
If someone repents but can’t do restitution, so the debt can’t be paid back, you should be merciful and forgive and count it as paid.
If someone doesn’t repent, leave the vengeance to the Lord.

That’s all Bible, and if you are familiar with it you can find verses for it (at work right now, can’t search verses)

Sometimes I think the emotional hurt is not necessarily unforgiving heart but lack of trust in God.

Interesting experience: once someone did wrong to me, and instead of fight it in anger I left it in God’s hands, for reals, and I had peace, even when dealing with the one that did wrong.
However, after a while, God showed me that the person that did “wrong” actually was innocent and it was just the result of circumstances, and he did what was sensible at the time.
