Totaly overthinking it. she might is a little bored about you cause she gave you so much IOI and you didnt approach her intimate , like going for a date or calling here to your house etc. The best think you can do is call her and say to her "we must meet for talk" if she is presistant and asks about the reason just say "i cant tell you on the phone, but its about a girl" BAM! you are interesting again! so you going to meet her make it seem like a date, then just talk to her us you would do with a friend of yours about HER , she will start and get the idea that you propably be talking about her and that she is the one you are talking about, if you get that feeling just say " i will meet her later, what you think i must do? " whatever she says make it with her right away and put an smile on
I am not an pua but i have made i many times and it worked for 100% its a psycho game, and woman need that kind of games.
P.s. sry for my bad english
