<human>: My dating past is basically non-existent. I recently moved to a new city and met a seriously fantastic girl who went to grad school with some of my old college roommates and best friends. They would kinda joke about setting me up with her a few years before I met her, and I was always somewhat dismissive, having no idea that I would one day move to this city and get to know her well.
Turns out, she was somewhat interested in me from the beginning (found out through others) even before I really started getting interested in her. I was afraid the window had passed, but recently I've started to see that she seems like she would still be open to something.

Everything sounds awesome right? I'm just lost. I don't know how to ask her out. She's a PhD student and her schedule is super odd, but really I've hung out with her one on one multiple times now and have had several opportunities to tell her how I feel. It's intermittent though, and I don't always see her. I think the problem is I've never done something like this before. I really like her and don't want to screw it up.

Basically what I want to know, should I ask her on a date...or just tell her i really like spending time with her and want this to go somewhere? I feel like a date is for getting to know someone, but I already know her pretty well at this point. She might even be frustrated I haven't said something, I don't know. Every time I'm with her and think I'm going to say something, I just freeze. The thing is, I'm not even awkward around her, like I can talk freely and have a good time (and I think she does too, because she certainly seems to enjoy being around me). I really have nothing to fear, yet I can't seem to do anything because I'm thinking too much.

Can you provide a brief overview of the text?
<bot>: How do I slow the hell down in my racing thoughts and say something to a girl I've gotten to know well over the past 6 months?
