Atleast you got the Option. My Nadia bugged out on me and pretty much forced a wedding.
I'm a pure lightside Shadow (hmm), never took the flirt option, heck, my Jedi took a -300ish total affection hit when Nadia was forced on to my Jedi for Padawan training.
Anyways, I dont' know how, but it got to a point in the conversation where All 3 options were just wrong for a lightside Jedi to take.
