Well then instead of playnig her game and not being honest....let her know that you still love her and it's going to be hard for you to be around her and act like yuo dont care. Since you know that it's over, do this, tell her you wanna stay friends (which is up to you) but take a long vacation from her. Cut all contact for a good week (trust me, it's longer than it sounds) and then avoid long convos with her.
