Sounds like you are being a really good friend to him, you are doing such a great job considering how things are between you two.

I also tried to read on the Mr Nice Guy Syndrome, but I cannot concentrate at the moment. I will try again though, it sounds really interesting.

"There's nothing sadder than a conman conning himself"

“There is freedom waiting for you,
On the breezes of the sky,
And you ask "What if I fall?"
Oh but my darling,
What if you fly?”
