I can see you being disappointed, knowing that you will never have her for more than friendship, but you have put too much into her being a friend if you ask me.
Now that there is no reason for any more false hope, its time to get back to the other areas of your life, and making new friends, and leave her alone to be happy with her life, and you be happy for her.
You may be shy, but that's no excuse not to deal with your feelings in a mature way, without the excuses.
I was trying to convince her by saying that as destiny bought us together 2 yrs before... same way we'll meet each other in future again if it's written in our destiny. She told me that all this is crap
