I dated this guy almost 2 years ago. We dated 2 different times but not for very long. He cheated on me with 4 different girls. I was extremely attracted to him. We broke up the day after valentines day in 2009 because his best friend told me about the girls. I had completely forgotten about him until I came across his facebook today and it was him kissing another girl, and I started crying. Why am I doing this? am I still not over him?
