Robbie

Did Don Grady want to leave the show after Season 11? Did Don Grady ever make an appearance in Season 12? Katie was thinking about getting a divorce because Robbie was gone so long. If there had been a Season 13, would she have divorced and began dating other men?

Wow, there's a whole new twist to the show I never thought of. Imagine a season that Katie's divorced Rob and now spends each week dating a different guy (just the way Rob had a different girl every week). She'd probably have to move out of the Douglas house and become an outcast and live in the seamy parts of L.A. along with her brats, I mean angels.

Kate and Her Three Sons: The Spinoff Series

Hold on a minute - to my recollection, Katie continued to love Rob in the final 2 seasons and divorce thoughts were a million miles away. Rob was in the army reserves -- you folks are acting as if he abandoned Katie and the boys...!

C'mon, it's fun to speculate on Tina's character doing the wild thing with a host of guest stars, but it's as far away from actuality as you can get!!

In the third-to-last episode of the series, there is an episode called Lonesome Katie where she talks to her friends about possibly living her own life, without Robbie.

And according to trivia, the show considered having Katie and Robbie divorce or to even kill Robbie off. So if the show had continued, there is a very good chance that Katie would have indeed moved on.
