<human>: I've been talking with this girl, we used to work together, and she's recently single. I told her I liked her and asked her out about 2 weeks ago.

Since then we've been texting/flirting, she sent me a picture of her in her underwear, it seemed everything was going great. 
I asked her if I was gonna see her last weekend and she said she was just too busy. 

She then gave me very short answers to the next couple texts and I asked her wednesday if she wanted to go out Friday (yesterday) and got no reply. After a couple hours of no reply I texted "hello?" And still nothing. 

So now I'm wondering what I should do. Today is Saturday, I haven't texted her since Wednesday. I'd really like to see her, and I'm really into her. But we no longer work together so I don't see her out in real life anymore. I'd like to ask her why she's ignoring me, but don't want to come off as needy or playing the victim.

Can you condense the text into a few key points?
<bot>: How can I ask a girl, who was seemingly into me, why she's suddenly ignoring me without putting her off?
