Holy shit man chill out! I can tell right now you're way too worried about getting a gf! You're so over thinking this if the girls into you go straight into qualification. Cut the B.S. and remember one line: "so... what do you have going for you more than your looks?" Then just ask lame questions about movies, goals, dreams, travel blah blah blah you're in A3 (qualification) this is where everything starts heading down hill. Chill out go back in there and approach it as just getting to know some one. If she's giving you IOI's you're in. period. That's the hardest part of game is getting the IOI's Relax and let go. I recommend staying single and building up a few options for yourself. When you have a few girls to choose from this anxiety goes away.
