Leaving personal items behind is a sign of comfort, and nothing more; unless she's the controlling type, and planted items just to have an excuse to call you back. It's simple psychology: if you don't feel safe, you'll act more guarded/paranoid. If you don't plan to come back to a place, you'll hold tighter/keep better guard over your belongings. She was comfortable enough around you to let her guard down.
If you don't want to fall for her, then you need to stop seeing her. That's the only sure way.

Who cares if your the rebound dude, go and get laid. Don't even worry about her intentions unless she's a gold digger and your rich. Get what you want, let her worry about what she does and does not want.
