Hello Everyone. I've been reading the forums and studying PUA for months now so I am not completely new. However, I have yet to post much, but I've done a lot of reading and used what I've learned in the field. I need your advice on my current situation. Here is the story:

This year I'm a sophomore in college. Last year I was single but certainly not devoid of girls in my life even though I had little knowledge of the game. This year I'm single again, but this time I have PUA knowledge (I studied over the summer, haha). Since the start of this year my Ex-GF from highschool and I have been hanging out on the weekends and going to parties, etc. In highschool we dated for over a year and it was a healthy relationship until I realized that it was time for me to grow up and that I couldn't do it while I was in the relationship. So I broke up with her and she was a bit heartbroken, but our friendship survived. But that was back in my AFC days.

So we went off to college at the same University and didnt talk much. She got a boyfriend and I stayed single, but had a great time with some different girls, haha. My Ex stayed with her new boyfriend the whole year and through the summer and their relationship continued through to this semester as well. Even though they were together my Ex and I and another girl (my senior prom date, haha) hung out as friends and even partied at my Ex’s boyfriend’s house. Recently my Ex and her boyfriend broke up; good news for me  Now I’m pretty sure I played a role in the breakup. Whenever we’d hang out I’d be alpha and treat her with a PUA attitude.

Knowing they’d broken up (thanks facebook feed) I kept up some text dialogue between us. Last saturday I texted her while out partying and set it up so that when I left I’d go to her apartment and make some things happen. Turns out there was a party at someone’s apartment in her building that we heard so I told her “We going to that party” and we went. Turns out there were a bunch of people there that I knew so going to the random party and knowing people there was some serious DHV. So after that we went back to her place, had some good conversation, then I said “You know what we haven’t done in a while?” and moved in for the kiss. So I hooked up with her, nothing more than a long make out session with some sexual touching. I escalated to the level of what I felt was appropriate then we slept there together. When I left in the morning I thought everything was good to go. The goodbye-kiss was the most genuine kiss I’d shared with someone in a long long time.

The next day and during the week I waited to text or talk to her until Thursday because I figured I know her well enough and that I didn’t want to look needy. Also I didn’t think she was going anywhere and I’m super loaded with work this semester so I have virtually no time to do what I want for most of the week. I regret not texting her something light and funny the next day, but what can I do now. The text I sent her Thursday was hilarious and related back to the night we had Saturday. I basically told her she owed me something based on the night’s experiences. No response. Now I know I shouldn’t care about these things, but I actually appreciate this girl and have known her for quite some time and so I feel there are higher stakes. Maybe I just have a serious case of oneitis. I was confused, but I knew not to text anything if she didn’t respond. Two days later I texted her again because I actually needed to borrow someone’s hairdryer, haha. The text dialogue was basically this:
Me: Alright you’re going to need to let me borrow your hair dryer
Her: What for?
Me: Windows
Her: Care to clarify?
Me: To defeat old man winters. I’m winterizing
Her: Gotcha.
Me: Sweet

I know I could have had better responses but her lack of response last time and her not-so-friendly responses here didn’t have me in the mood. Honestly I sort of messed up there, but its still a mystery to me why she wasn’t more friendly based on the experience we had the proceeding weekend. So now I plan to tell her that I wasn’t kidding about the hairdryer and I know that I’ll end up at her place picking that up or she’ll end up dropping it off at my house. Either way I want to repair the present void between us. This is where I need all your brilliant advice. What should my next move be? If I should go get the hair dryer how should I act? I want to talk to her about it but don’t know if that’s the right move here. I actually care about this girl so keep that in mind. This is the first time in a long time that a girl has actually had any power over me emotionally. Any suggestions?
