Forgiveness is for OUR benefit. It is for OUR good.
In Luke 6:27-35 Jesus says:
“But this I say to you who hear: Love your enemies, do good to those who hate you, bless those who curse you, and pray for those who spitefully use you. To him who strikes you on the one cheek, offer the other also. And from him who takes away your cloak, do not withhold your tunic either. Give to everyone who asks of you. And from him who takes away your goods do not ask them back.
“And just as you want men to do to you, you also do to them likewise. But if you love those who love you, what credit is that to you? For even sinners love those who love them.
“And if you do good to those who do good to you, what credit is that to you? For even sinners do the same. And if you lend to those from whom you hope to receive back, what credit is that to you? For even sinners lend to sinners to receive as much back.
“But love your enemies, do good, and lend, hoping for nothing in return; and your reward will be great, and you will be sons of the Highest. For He is kind to the unthankful and evil.”
In summary … forgiving those who hurt us is great wisdom. We learn not to take immediate revenge on that person who wronged us despite what they may have done. Things will only get worse. Although it is hard, try to communicate as peacefully as you can without escalating the problem further if presented correctly. Life is too short. Forgive! If they refuse, at least you tried. Regardless of trying to be at peace, never overdo it. Pray, and let the Lord, handle it. You know you did what you knew is best.
Finally … when we forgive our enemies and choose to love them, God promises to reward us for it!
