How do I deal with this...?

My best friend was on my ex boyfriend's facebook page. I tell her not to read me anything from his page but she said I should probably know. My ex boyfriend is an excellent piano player. We would sit at the piano for hours and he would teach me and he would play. At my friends high school graduation, we got separated I had my friends to go with, he with his and I later went to find him and he was with my best friend at the moment making out and excessively hugging. That's how we broke up. But it wasn't physically said or explained. But on his facebook page she showed me that he was writing a song for her from scratch. It deeply hurts me that he's like that...how do I deal with this...please help me..
