<human>: Preface: I know I am young. Please do not let this fact change your advice or affect it in any way. 

It goes like this. My girlfriend[17/f] and I [16/m] have been dating for just under 6 months. She really likes me, and sometimes I just don't really want to talk to her. I think I like her, but I am not really sure. On the other hand, I have my best friend [16/f] who I have known for years. She goes to my church and we hang out together when we do anything there, with a few other friends. A few years back, we tried dating, but we were too young and it didn't work out, so we just became off and on friends. Recently, about a month ago we started really talking again, I can't really remember why. Soon after her boyfriend of a week and her went through a really bad breakup (which he had a bad rep for, she didn't know). I helped talk her through it, and we got even closer. A week ago we, with a group of other high schoolers from our church went on a trip to Florida. She and I became even closer, and I discovered I still had feelings for her. She makes me happy and laugh,but in turns she makes me nervous about how she will respond to what I say, and how she reacts to what I do. My girlfriend just seems comfortable, and sometimes our dates kind of seem sad. I really don't know who I really like, and how much, or how to deal with it. I am fairly sure my friend has no feelings for me.

Can you condense the text into a few key points?
<bot>: my girlfriend doesn't really compare to a friend of mine, and I am not sure who I like, or how much. I have never broken up with anyone before, and I really have no idea what I am doing.
