What is the whole thing, then, if not a futile expenditure of energy and a mockery of emotions? What is the use of being with a person whom you hold grudges against? What is the point of pretending to love a person whom, you know deep down, you will never be able to give yourself to, completely?
The first step towards forgiveness is convincing yourself to forgive. The question whether forgiveness is fair to you or not, after all that has been said and done, is simple. Ask yourself if your mind will ever be at peace if you don’t let it go. Most assuredly the answer will be no. Keeping grudges can be more harmful than any other thing in this world. Holding grudges gives rise to hatred, and isn’t hatred the main cause of everything wrong in this world? Why make yourself sad? Why put yourself through so much trouble? It is also important to ask yourself what is more important to you- the person in question or your ego. Then you’ll have your answer. Yes, forgiveness is fair to you. You deserve to be able to forgive!
So, let it go. If you cannot forgive somebody, if you think that the intensity of their crime defiles all humanity, it is fine to not want to see their face ever again. But in your heart, you have to forget. If someone has done unimaginably bad things to you, of course they don’t deserve forgiveness. But, you do, don’t you? What will hating them do, other than make you miserable? What good will possibly come from it? Isn’t it better to maybe not have them in your life but also hold nothing against them? Forgiveness is smiling genuinely at the enemy. It takes time to achieve but when you do achieve it, nobody will be more peaceful than you.
The ultimate choice lies with you: you can forgive and move on, or be eternally stuck in time.
