Not going to work. The guy has to move on with his life, staying and trying to be friends is like self-torture.

Why are you even in contact with her? The best thing to do after a break up is to remove said person from your life, at least IMHO.
The fact that she has a new guy should be a bigger sign for you that you won't be getting back together, and that it's time to move on.
Trust me bro, I've been there, and all I achieved by hanging on to hope that we'd get back together was prolong my own suffering.
