Girl i like with a cheating bf.. not sure how to play it now?

It may not be intentional but she is playing you. She is not going to leave her BF and if she does it will not be for you. Sorry honey but you have slipped into the friend role; once there you're done. Women are not fickle, we know what we want and will go for it. If she wanted you then she would be with you. He's a bad boy, she's drawn to bad boys and she is not going to leave him. Leave this woman alone and Please!!!! do not get caught up in her drama. If you try to play the hero it will turn out badly for you; and you will be left confused. Move On!!!
