<human>: Could you distill the essence of the text into 1-3 sentences?

Alright so I recently started "talking" to this girl and she was my first kiss and basically the farthest I've ever got with a girl. We're both 16 and I'm lost as to how to make this become official. It's only been a week since we first kissed and I've only known her for 2 weeks so I'm not asking for it to be official right now, but I feel as if I'm losing her. I don't know why, but I just feel like I do. We talk on the phone constantly and we've gotten really comfortable with talking about private stuff. We have gotten accustomed to the inevitable silence when we run out of things to say sometimes. But I still feel as if I'm doing something wrong.
We're supposed to be going on our first official date next week but I don't know if she will want to be with me for that long. I have no intentions of leaving her, but I think she has intentions for leaving me. I know I'm rambling on right so please bear with me. She has had a past with just losing interest in guys really fast because she finds faults that she can't stand but so far she hasn't found any of those deal breakers with me, but she want's to wait until she knows all my quirks and even though I don't think I have any deal breakers, I'm afraid that she'll find one. We've also talked to each other everyday for the past week and I'm running out of things to talk about without mundane conversation. if we are doing an activity we're fine; if we are just talking it can become very difficult to continue the conversation.
I think I'm overreacting a lot as well, seeing as how I am desperate to not fuck up my first relationship. I don't know how the hell I'm supposed to make this work. Can someone please help?
<bot>: I have no experience and I'm trying to go from the talking phase to dating, and I feel that I'm losing her
