I wouldn't give her another chance quite yet. What you're doing now is smart, though. Stay in contact, but keep your distance for the time begin, until she can figure out what she wants to do.
Everyone here is right - If there is any chance that you both decide to get back together, I would lay down the foundation of the relationship and let her know that talking to her ex is something that isn't appropriate when she is with you.
This is exactly why if she needs to talk to him, she should do it now. I view it as disrespectful to be involved in a relationship with someone, yet still be speaking to or seeing an ex while in that relationship.
Stay on it Ben - You're doing great so far!
