I meant all girls in the world, but your pack is a good start

How often haven't we all heard 'this girl makes me forget about my game, I suck when I am close to her, even though I want her so badly'? The girl you really want only comes when you've already had the rest of the world. Instead, focus on getting some other chicks. You can easily have 4 or 5 girls who you're gaming at a time.
It's what I do too. I game chicks, I learn from my mistakes, I try to correct myself, all for this higher purpose: This one girl, whom I will see again this summer. My 10.
My problem isn't getting the HB6 and 7s, I'm a natural around them, but the more pretty girls are the ones that were out of my league. Nowadays I know how to get them, but the low amount of hot girls gameable in my area keeps me back.
Keep in mind that it might be (and feel) strange if you suddenly start acting 'so cool' around these women. They might notice your incongruent if you tell them you can't come. It is something that has to progress slowly, but noticeable. Get some other friends at your university, have fun with them too instead of being 24/7 around your pack (like zendelo says).
Note on the boyfriend-thing: You can build as much sexual tension as you'd like, if you don't escalate, nothing happened. You can game the 3 girls, get them attracted, touch them everywhere (okay, not everywhere, but you get what I mean), but as long as you don't kiss them, the boyfriend-factor can't get you in trouble. Most of the times the girl will tell you when too stop if she has a BF.
