Why does my heart keep breaking? How to make it stop?

You see, I like this guy. We use to be friends. Like super close friends. We almost kissed last year! I still like him but he has these new friends he replaced me with. And he told my friend on the day that marked 3 years we were friends that he didn't care about our friendship and he rather hang out with Jade and Shelby. Mine and my friends replacements. He doesn't even care. He has totally changed in his actions around me. I'm his 7th choice. Not first. 7th. The last conversation we had was during a movie which was in December. The day before winter break. His hand was next to mine. We talk through the whole thing. I mean we didn't even watch it. It was just Aly and Trenton time. Like the old days. That's what I want back. My friend. Please help me. (P.S. I keep on crying and listening to the end of Don't forget by: Demi Lovato)
