Struggle ~.~

What happen to me??
I don't know. Tomorrow is my last paper ed.. I'm not struggling about the studies, but with some other friendship problem..
She is my best friend and he was my friend.
They date since the end of last year. Her number was given by me for him. I thought he was kidding with me when he asked for her number. And I'm confident that she wont bother about him.
But, I'm wrong, wrong , wrong.
I'm totally wrong. They date.
Yea, he's quite a nice friend, but according to my knowledge, he's not a good boy friend. He had date with many gals before and always flitering with other girls too..
She is my very best friend that I get to know in the uni..
I'm so afraid that she'll get hurt..
I cant really accept their relationship..
What's going wrong with me??

Don wanna to think so much anymore..
Just let everything be what it should be..
God bless..
