I kinda used someone before once my bf cheated on me & i wanted to onyesha that b*tch how it felt so i used someone but i told him i was using him so it was all fine... ....but if he didnt know he was being used i dont think it means i would be shallow if he didnt know, it'd just mean they're a big fat lying bitch, kahaba is all..not neesarily the lack of knowledge
