You were ghost girlfriend before a new recruit you thought nothing of it until you noticed ghost and her getting closer while you both were separating 

You had walked in on them doing it in your bedroom you had stood there frozen shocked and hurt while the just looked at you while putting on his clothes you ran out and that moment spread like wildfire everyone hated them you bff went and yelled at him
 
She yelled curse words at him while you were sobbing in her arms at the sight of him
