You didn't get played. She didn't plot and execute a scheme to have a relationship with you. She's being true to herself. That should scare you.
When you bond with someone like that, you don't come away unscathed. You don't just divorce and move on. I strongly suggest you get an IC. You're in an incredibly difficult place, and an Internet forum isn't enough. Hardly.
