<human>: Anyone else big overthinkers in here? You blow situations way out of proportion and create immovable mountains where there are none? That's me! And I need your help.

Here's the situation (forgive me if you think I suck):
I [21M] asked this girl [24] out not too long ago, and she said yes. I offered to take her out that Saturday, but it was a busy week. Currently these couple weeks are also busy (genuinely), and it's also Thanksgiving (CA).

When she said yes initially, I got the impression she wasn't totally into it. It wasn't awkward, I'm just not sure she's interested. It's been a week or so since I asked her out, and nothing's changed. It's not weird; we see each other a lot and it's fine, it just feels like I'm in no-man's land. It seems like she's hoping I'll just let it go.

I do suffer from confidence issues but my gut says she's not interested, and I should leave this alone. If she wanted to go out, she'd bring it up at some point. I thought I'd just play it by ear and leave the ball in her court (but not hold on to any hope of it being returned). Or I could ask if I could take her out this Saturday and potentially make a neutral situation a negative one.

Has anyone experienced a similar situation before? How did you / would you handle it?

Can you condense the text into a few key points?
<bot>: I asked a girl out, am now in first-date purgatory, and don't know how to get out.
