A Girl/Boy Who stands by some one side no matter what. Even if that person is treating you badly you still remain there for them or your bf/gf cheating on u and hurting you you still give them chances and still remain by there side and continue to be there for them.
They use Her all the time but she still be by there side. Defined loyalty
Loyalty is basically the word "investment" but with an opinion or point of view attached.
Loyalty is treated like a virtue, but it can't inherently be one, by itself. Case in point: People in hate groups are very loyal. So is someone with Stockholm Syndrome.
Investing your time and energy in a person or idea, over time...is a completely neutral act without a who, what or why attached.
Loyalty is such a dubious, perspective based word. It's right up there with "honor". Other virtues like love and honesty, are intrinsically valuable even if you love or are honest with the wrong person. This is not the case with loyalty. Being loyal to the wrong people is often based on fear, codependence, or the "birds of a feather" principle.
