"The Big Bang Theory" star Jim Parsons decided that after 12 seasons it was time for him to say goodbye to Sheldon Cooper and the CBS sitcom. A deal that would have reportedly nabbed the actor more than $50 million over two years couldn't convince the actor to stay.

Even in its 11th season, "The Big Bang Theory" was still the most-watched show on television with an average of 18.6 million viewers, according to Deadline. Despite the strong ratings, CBS decided that with Parson's exit it was time to end the show.

Parsons' choice to leave clearly wasn't an easy one. In a lengthy and heartfelt post on Instagram, he thanked everyone involved with the show, as well as the fans.

"I will miss all of you and all of this more than I can say and more than I can know at this time," he wrote.

Of course, Parsons isn't the only actor to make the difficult decision to leave a hit show.
