Before I say anything, I am only in High School.

I am not going to lie, I have some fuckin good text game. I know this isn't key to the game, but I am only in High School, so conversation has to start somewhere if you know what I mean.
Anyways, I have been texting this girl for about a week now. I wasn't sure if she was into me, but she's fucking hot! During that week, I talked to her about this club we are both going to and I said: "It'll be a good night." She said: "I'll make it a damn good night!" In this context, we were speaking about dancing with each other. At that point that was one of my only IOI's. Recently, I was at this party and took a picture of myself; she wanted to see the picture, so I sent it to her. She said: "Oh nice your really hot haha." At that point, I decided to use one of Arash's techniques and invite her to "come along" so to speak, so I told her I was going to a party and needed a cute girl to come with me. She replied back and said "Maybe blah blah blah possibly "

Now one of my flaws is keeping the girl... I am really good at getting girls, but it's keeping them. I believe I am a good looking guy. I have been hitting the gym a lot, I play football, and I have been trying to incorporate the "confident" player aspect into my lifestyle.

How do I execute this situation now that she has shown interest?

Blue forty two..set set HIKE!

High school and already escalating. Nice one. Reminds me of me. Well...take it slow and most importantly do NOT be aggressive. I imagine a football player may be like that or unaware of that effect.

Obviously kino escalate her. You don't NEED to take her to some party ...or social even. She can have fun with you anywhere.
