It had been claimed the actor was in talks to reprise his role as the Duke Of Hastings in season three of the Netflix period drama.
"I do not want my diagnosis to be a self-fulfilling prophecy," said the actor who plays Lady Crane on the hit Netflix series. "I want to survive."
"It really felt like the perfect moment."
The couple follow in the footsteps of Daphne Bridgerton and Simon Bassett and Anthony Bridgerton and Kate Sharma.
Filming on the next series of the hit Netflix show will begin this summer.
