I agree with LH19...it appears as though she's hiding things from you and is trying to make you feel bad for wanting to see her text messages. IF she was truly remorseful and wanted to R, she'd be doing what it takes to EARN your trust back.
You need to detach and focus on yourself. Remember the pursuit/distance relationship...it's your time to distance yourself and let her pursue you. She needs to show you with her ACTIONS and be CONSISTENT over TIME.
