There are 3 endings for both Anna and David that I am hoping for, and here they are in order.....
Anna.
Ending 1, Anna divorces David, and becomes "Daddy" Hank's good girl.
Ending 2, same as before, but Marvin claims her instead.
Ending 3, Anna and David get their happily ever after, with their relationship stronger than ever.
David.
Ending 1, Kendra's plan succeeds, Anna divorced David and Kendra finally claims what is rightfully hers.
Ending 2, Kendra's plan half succeeds, Anna divorced David, but David ends up falling for Alexia, and Alexia does the same, ending with them starting a new relationship.
Ending 3, Anna's happy ever after ending.
Time will tell if those possibilties may happen, but I am hopeful for them.
