Girl at school is obviously into me, we flirt on-and-off for a few weeks. I fail to capitalize. Lately, she's lost interest and pretty much ignores me.

Alright, so I know what needs to be done (pay attention to her, put forth clear hints that I wanna fuck etc etc); but since she's being so distant, what's an effective way to approach her without awkwardness? (since awkwardness can spoil everything in such a delicate situation)

Better yet, is there a non-verbal, more subtle way to let her know I'm still down when passing her in corridors etc, so that perhaps she will approach me?

just make eye contact, smile, grab her hand, and hold it

What happens when you dont escalate with women.
