I don't agree with how
yossa999 put it and no, we are not
responsible for another person's feelings, but acting as if Bella's decision to reject a Fuckface who gets involved with her co-worker
in her car is illogical, is
itself a logical fallacy. Her feelings may be the reason she rejects him but her decision is entirely logical because she doesn't wish to be involved with a young adult who
evidently can't keep his dick in his pants. It is defined repetitively in the narrative that it just isn't in her character to get involved with an obvious womanizer. I imagine all the MC's dalliances will be scrutinized by her once she learns of them.
