Have you heard of Prince EA?
He is amazing and his videos and messages full of hope and inspiration to improve the life you are living.
This video is one of my favourites, as not forgiving people means that you carry around bitterness that affects day to day living. It's like a weight that threatens to pull you through the floorboards at any given moment, or a rucksack so full of boulders it physically hurts to go anywhere.
The message is that if we put ourselves into the shoes of the people that have 'wronged' us or caused us misery, had their upbringing, events that happened to them, thoughts they have had reinforced until they become their 'truth', pain they have felt, would we act and think in the same way? (lots of nodding going on)

It doesn't mean putting up with an abusive relationship, you don't even have to talk with that person again, just let it go, don't let bitterness put you in a prison inside your head.
There is one earth, but there are billions of worlds
The mind of every single person is unique and full of their own truths that any outsider couldn't even hope to fathom.
I have spent many a year trying to work out why certain people think and act they way they do, even tried to change and influence that, but ultimately change is down to the individual person, not someone else.
Thinking about this advice and trying to put myself in their shoes, I may have an inkling of why they acted they way they did. There is empathy there and forgiveness.
Forgiveness is not weak.
It takes a strong and wise person to forgive, to choose to be better, instead of bitter.
You have to remember though, sometimes the person you need to forgive is you.
