Oh man...
Ok, this is how you should act around her: do whatever the fvck you want and stop caring what she thinks, because you're never going to taste her poonani. Just don't humiliate yourself again.
The main thing you need to do is stop watching Friends and stop gushing out your emotions and telling girls "how you feel", especially on an online messenger. That sh1t doesn't work and just sabotages you forever, trust me, I've been there. You've got a long way to go my friend, so start reading the DJ bible.
NEVER TELL GIRLS HOW YOU FEEL! You kill any mystery and the chase. SHOW GIRLS YOU ARE ATTRACTED TO THEM, DONT TELL THEM, so use Kino, sexuality, be a good listener etc.
Forget about this girl, you've been friendzoned long ago, no you are not the best option for her either, because you've acted like a pvssy, and girls don't like pvssys.
Most importantly read the DJ bible, because you don't understand basic concepts. Sorry for being harsh, but you need to get the blunt lesson from this, and i don't like to sugar the pill.
