Is she only free-roaming? Because I would suggest you have a proper enclosure for her, too. She's not going to get adequate heat, humidity, and UVB if she's always free-roaming. Not to say that letting her every now and then is a bad thing, I let my rhino run around all the time. But definitely make sure you have a proper set up, and iguana-proof the place so she can't get out again. ;3
If she still isn't trusting you, just remember: baby steps!
