Friends with your ex...?

I really want to stay friends with my ex boyfriend. It was a mutual break up. How do I go about doing this?Friends with your ex...?
Which is the reason to be friends again?.If you have a reason is because something very inside you is making noise.Remember this, something was there.Something very nice in the beginning,something magic.Always a memory might be around you like ghost.Is not easy, but you have the right to try It.Think about it.
