So there is this girl at school that a friend and I approached months ago. She was rally attractive and would catch me starring at her at times. One day me and my friend decided to approach her and introduce ourselves. She seemed really shy but content, I thought it was because of her attraction towards me but instead she was actually really into my friend (she barely even noticed me and i was doing mos of the talking). So I left it alone and when I would see her around I litterally would ignore her and not acknowledge her presence. Its been 3 months now and I continue not to speak to her but I lately I ALWAYS see her starring at me from the corner of my eye when I pass her in the hallways. I'm considering reapproaching her now that she has forgotten about my friend. What should I say to open and talk to her more?
