Hi rodrigo, im happy you want to share your experience through this.
I ever loved someone for 7 years, at first only adore that guy, but the feeling growing.
And in the end he choose another instead me in front of him.
im crying for 2 weeks and after that completely move on, but still the scars in me.
All i know is you must give all your complaint, like what you feels, what you think, why it happen, why this, that, all about that. Just spurt it out everything, let it go, not keeping inside the feeling right now, let it go and accept it. i know it was hurt.
But you must do that, or it will kill you slowly. dont focus on her that much, you still have a friends and families who support you, you got a life to move on. It takes time to heal, but dont let that feeling ate you up.

If i can move on, so you do!
Anne
