By the Way - Lovesongs, #1.5

Antoine and Wally have been best friends since college. They do everything together-work, play, relax, live. Minus the blight that is Wally's wife, and the unhappiness she brings him, their lives are grand. But then Wally files for divorce, and his wife drops a bombshell he never expected, and Antoine realizes that the life he'd always imagined with the best friend he's always secretly loved has been taken away from him a second time.
