You think he has asked her out by now? Considering it's been 7 days. I had this problem with my crush, totally ignored me. Then I moved and I never got a chance to fix things with her. But for me it's a different situation because I'm a girl and she's a girl. You get the idea...
buy her something, leave a note, but dont mention ur name only hints xd Besides even thought most of girls are picky irl, u should just try atleast stay her friend and help her out. Eventually she will stop from ignoring you.
I'm lost and daddy direction if you called me fat the only thing you would be getting out of it was a fist to your face!
