Forgive and Forget!
Apologizing, does not always mean that you're wrong and the other person is right. It just means that you value your relationship more than your ego-
However even if how many times you say sorry to that person if he/she is not accepting it, its kinda destroying your ego, at the end you'll just suffer from the pain even if you value your relationship. :)
It’s hard to say you’re sorry. And it can be even harder when someone doesn’t accept your apology. But that’s ok. People are allowed to not accept your apology or need some time to think. You can’t control what they say or do, but you can control what you say and do. So stay steady and calm, manage your emotions of rejection and hurt, and show your apology through consistent actions.
They will always do that, Everytime for the forgiveness. But not even sure what is the real lesson, after giving the forgive and forget. Sometimes they said Never dies.
