<human>: So, I'm a nerdy dude. I go to the center at a magnet school in the USA. I do a lot of computers, math, and running.

During track season, I met this cute girl who is a year younger than me, and after a week I asked her on a date.

She's incredibly funny, smart, and interesting, but she mentioned some stuff (on the first date) that really troubled me and I haven't been able to stop thinking about it.

She mentioned that throughout middle school and the freshman year of highschool (She's a sophomore now) she was really into various drugs, and snuck out on multiple occasions when she was 14 to go to clubs/have sex with dudes who were 18-20.

Funny first date right?

I'm a nerdy kid, virgin, etc., and would never judge her for her past actions because I try to not be a dick. The thing that really troubles me, though, is why she's gone on two more dates with me when it's kinda clear I never did any of the same stuff she did and I'm not really the kind of dude she would want to date. 

Also, I have no idea if she is still into all that stuff and what that means for a potential relationship. This leaves me wondering and worrying about a lot, as I have this thing where I cannot ever stop concentrating on something I can't figure out.

So, should I ask her about it? Do I have the right to know why she's decided she wants to date a nerdy track kid who couldn't even get the nerve to kiss her on the first 2 dates?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Amazing girl with has a past that troubles me, and I don't know if I should confront her/talk to her about it when we've only gone on 3 dates.
