A little analogy:
Your girlfriend say you "Marry me! Marry me! My dream is to be your wife. I won't let you down."
You answer "Yes, I love you too. Let's go married."
So you work on the wedding and spend a lot of money for the food, place, music...
Two days before the wedding, she continues to say that being your wife is her dream...
One day before the wedding, you learn in a tabloid that she is now with Brad Pitt and won't marry with you. She hasn't even told you that the wedding was canceled.
So, what will be your reaction ?
A) You're ing pissed.
B) You forgive her. How can you blame her, Brad Pitt is way cuter than you.
