Thanks guys, I definitely agree about being a little too aggressive on "Jesus I got it the first time..." I tend to forget about rewarding good behavior, it becomes too much of a game for me. Honestly, I would rather call versus text, but (I'm in college) all these girls live by texting... Anyways thanks for the advice!
P.S. I just received a text from this girl that I've been chatting up in class- HB9. She texted me "What are you doing" late at night (12:37 am) and I was having a boys night playing some poker, so that kind of played into my decision not to text her back. As well as I spoke to her the day before on Thursday and invited her to come to one of my girlfriends birthday parties, so I'm assuming she's coming to that (when I text her). It all played in to the decision of me not texting her back plus, in my opinion, although she obviously was interested, to not text her back and thus making her want me even more (and only make her think of me in the next day as to why I didn't respond, then her fantasy and imagination turns on

) and not in anyway appearing needy or that she's in control. I was tempted to text back, or at least text "Is this a booty call" for fun, but then decided not to as the best decision.
Anyways, lmk what you guys think about this. And I'm going to text her later tomorrow, I'm not sure yet what, but probably "We're meeting at Shashi's house at 9:30, come join." What do you guys think?
Cheers,
Seva
