<human>: So Friday night, I (male, mid 20s) asked my friend of about half a year (female, early 20s) out on a date at the end of the night. I've been developing feelings for her in the last month or so and have been wanting to explore a relationship.

I finally worked up the courage to ask her out, and was frankly prepared for her to reject me and say let's just be friends. What I wasn't expecting was what actually happened. She's normally very articulate and collected, but when I asked her out she seemingly became a little unglued. She seemed nervous suddenly, and frankly was rambling a bit. In the end she didn't answer my question, said "I don't know" a few times. I haven't seen this side of her before...and am not entirely sure what to make of it. I know when some girls say "idk" they really mean no...maybe that's the case here...I'm really not sure. After that we said good bye and she took off. She texted me an hour or so later and thanked me for dinner. I haven't heard from her since then. She is very busy with school/work...but I was sorta hoping for some sort of contact by now...

I guess my question is two fold. 

First, any opinions on her reaction are appreciated, cause I'm still a bit confused as to what to make of it. 

Secondly, I'm worried I've possibly lost her as a friend or freaked her out by asking her out. We're both supposed to  be at a social function about a week from now, but otherwise we don't have any plans to meet before then. I'm wondering if I should try to see her before then (I just want to see her and see if everything's okay...I wouldn't dare to try to force the issue again)...or if that would seem pushy or like I'm trying to force the issue or somehow weasel a date in or something. If she doesn't want to date me...I'll be disappointed of course, but I'll survive...I just don't want to lose her as a friend as well. 

Any advise is welcome!

Give me the gist of the text in a nutshell
<bot>: Asked a friend out, she said idk...not sure what to do now. I don't want to lose a friend.
