It's driving me insane!

All I had to do, was be honest and say I love her. and there, my best friend turned traitor and left. Its been 6 weeks since we split, 2 weeks into that, 4 weeks ago, I tried to fix the friendship, but she wouldnt listen. I stil think about her. Everyday, every night. I feel so betrayed but I'll stil welcome here back if she ever decides to forgive me. It hurts to be without her.
