Trying to Move On

How do you move on, after having someone in your life for a decade? My ex and I broke up, but we continued to date each other. Then he met a girl online (we continued to date), and is currently there with her. Through out everything he and I were best friends and remained close. Now after being back there for 3-4 days, she's become his new best friend, and now I'm just a friend to him. I just can't understand how you can be someone's best friend for years and have it be gone in the matter of only a few days. I'm trying to move on but it's so hard. I'm so sick of crying but I don't know what else to do.

I like this song, and hopefully you can relate to it.

P.S. I guess he didn't see what he had, and had to move on.
Like the song says, " All of memories keep you near "
But this song is more about her love's death.
