does it make her a bad person?

ok, so this involves 3 people. A girl, who we'll call Stacy, a boy we'll call Dallas, and another girl we'll call Ruby.

So Ruby had liked this guy, Dallas, for a long time, but Stacy, one of her good friends, also liked him. And Stacy was very open with the fact that she liked him and often complained to Ruby about how difficult it was for him not to like her back. Ruby never berkata anything about liking him too and she just listened to her friend talk about him. Eventually, Dallas asked Ruby out and she agreed. But Stacy never knew that Ruby liked him and now thinks she just mencuri him out from under her. But Stacy isn't allowed to tarikh untill she's 16 and Dallas never liked her like that.

Does that make Ruby a bad person/friend for going out with him?
