Toulouse-Lautrec: The greatest thing you'll ever learn, is just to love, and be loved in return.
Satine: Tell our story Christian, that way I'll-I'll always be with you.
Zidler: Send Christian away.
Satine: He will fight for me.
Zidler: Unless he believes that you don't love him.
Satine: What?
Zidler: You're a great actress, Satine. Make him believe that you don't love him.
Satine: No!
Zidler: Use your talent to save him! Hurt him, Satine. Hurt him to save him. There is no other way. The show must go on. We are creatures of the underworld. We can't afford to love.
Christian and Satine: Come what may, I will love you until my dying day.
Answer: He wallows in self-pity for a while, then eventually begins to write their story. There's no indication that he has any further links with the Moulin Rouge - it would probably be too painful for him. Christian actually states in the movie that the night Satine died was the last time he ever stepped foot in the Moulin Rouge.

In what scene did he state that I'm curious.
When he talks about going back there to see if she still loves him. Right before he goes back there that last time.
When Christian sneaks back in after having been tossed out, he says he returned to the Moulin Rouge one last time.
