1. You need to behave like a lover/boyfriend if you want that to be the context of your relationship with her. The primary way you do this is by touch. Guide her through a crowd, take her hand while you are walking, link arms while you are walking, preen her (move her hair away or adjust her clothing), rest your hand on her (could be her thigh, shoulder, knee whatever). To the outsider, does it look like you two are intimate with one another? no? you have fucked up.
  2. If a women likes you in any way, she will create a moment, not multiple moments, one single moment where you can either find your balls and kiss her or be a pussy and not. If that moment has passed and you didn't act, you have fucked up.
