OK I was trying to game HB9 2 grades below me and failed.
I was trying to game also one in my grade - failed.
and another HB8 a grade below me which I dated a distant friend of hers and failed too (I am not that good lol).
All of these girls live in the same half mile radios so I think I kind of burn my self out of my area...
For example there's a cute girl which I only saw on Facebook we got 6 friends in common one of them is the HB9 2 grades below me (she's from the same grade as her's) and she is also a friend of the girl 1 grade below me(the HB8) and she study in the same school as she does.

You see? I think I may ruined it before I even started and if I fail with her too they will talk about it eventually even though I really don't know how well she knows those two girl (I only know she's not a real close friend of them).

What do you think?

High school is a very different game than real life. Your social circles are much tighter and there is much more gossip. I would advise you to maintain a strong playful friendly frame and play conservatively. It isn't a bad thing to be friends with a hot girl, and just because you failed to lay a girl doesn't mean she can't be an asset to you.
