<human>: Can you provide a brief overview of the text?

I decided to go for it and ask out the girl I like, whom I've known for about 7 months, but I messed it up.

So I walked with her after school and when we normally split up and say good bye I asked "Hey, are you busy this weekend" and for whatever reason I just expected her to say "no, I'm not" and I'd ask "I was wondering if you'd wanna go out this weekend" and then she would either say no or yes.

Anyways, she said "I am, sorry" to which I had no reply because I was already nervous so I didn't really have a response because i had it planned out in my head, and just said "alright, see you on Monday!" And she said "have a good weekend" and we walked away.

So I almost did ask her out, but I was caught off guard because I somehow didn't expect her to be busy. 

So my questions are, should I ask her out again and be more direct? If so, when should I do it, how soon? And do you think she knew I was about to ask her out?
<bot>: I started asking out a girl, didn't ask the actual question because she said she was busy. When should I ask again?
