<human>: Give me a shortened version of the text

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.
<bot>: How can I ask a girl, who was seemingly into me, why she's suddenly ignoring me without putting her off?
