Is there any chance of getting back crush?

I met this girl online and we exchanged numbers, and we started joking around, then she mentioned she would love for me to see her bed, and I tried playing it off, but she insisted and it led to sexting, etc...Anyways, I texted her the next day and she ignored me for most of the week, and confronted me when she realized I was consistently looking at her profile on the site we met (I told friends I was depressed a girl I knew was ignoring me, and they wanted to see what she looked like), saying it was obvious I liked her more than I should. I pointed out that she was the one who came onto me, and how was it my fault, and she said it wasn't but she regretted doing what we did, so I said I didn't want her to be uncomfortable, but would like to remain friends, but it was her choice, and that's the last time I heard from her...I know it's over but I can't stop thinking about her, even though we never even met. Is there anything I can do?
