Bianca does not want any kind of commitment from James but when he gives her a watch , she " feels sick to her stomach " because she "feels" like it's a thank you for the fuck gift and he's ending it , when it was her that predicted the timeframe of their affair.
This here is why I get turned off of certain types of heroines , you didn't want commitment so why the hysterics when you think things are about to end ?
You either want something or you don't , it's confusing and annoying .
Ain't nobody got time for that !
