I'm sorry for it!
I was really close to this girl at my school. She really like this guy in a higher grade. About a year before, I liked a guy and she flirted with him only after she knew I had deep feelings for this boy. So I saw the guy she liked was on FaceBook one day, and I instant messaged him and asked him if he want to go to the movies. He said yes and met me there that night. We made out for at least an hour and I dated him for two weeks, after she found out she cried for hours. I thought at the time that will teacher her to mess with my love life, but now I feel bad an guilty.
