Why did Courtney try to change Duncan in TDA?
This has been on my mind for a while now. In the second half of TDA Courtney tried to change him. However in TDI she still liked him despite his behavior. Is it because:
A: She's a perfectionist and wanted Duncan to be the perfect boyfriend
B: It was a part of her antagonist role in TDA
C: She thought Duncan wouldn't break up with her (because of her rules/contract) and hook up with Gwen
Or the reason could be completely unknown thanks to the writers.
Anyway, I'd like to know what you guys think. Why did Courtney try to change Duncan in TDA?
