Thank you all for your answers, it really means a lot. I can relate to some of answers that have been given here.
The truth is, sometimes it's hard to forgive or forget, we may find some things that allows us to see things in a different perspective,to find peace inside, like some of you said with the meditation, yoga, but on the other hand and think that only can happen after we "grief" from all the pain we feel. I think i can forgive, give chances to other people, depending on the situation, I've forgiven my friend over and over, but then it reached a point i couldn't anymore, those things were harming me, bringing up some things from the past that was painful. But i Don't ever forget, ever. I don't allow myself to, it's like i make myself to remember those things over and over, and i think it is because of some of the things someone here already said that this is a protection, i never thought it that way, and I've been asking myself why i don't forget and why keep remembering all these things.
In other different situations, they are some things we can't really forgive, no matter how hard we try. I give the example of my father, he has betrayed my mom over and over and it confuses me how can she forgive cause she cannot forget, i know it, she said to me. I can't forgive him, not totally, because at some point he did want to leave us and start a new family, and when i was younger he even introduce some woman to me, while he was still married with my mom. I really can't forgive him. But i think i some day want to, i don't want him to pass way knowing i didn't forgive him. But it's so hard, because when i was 6, that was the first time i felt disgusted of my father because we was having sex with others womens (womens of a nightclub) and i will never forget that felling.

At the end of the day we all have different ways to forgive or forget someone, i wish you always find the better way to do that.
