My girlfriend and I recently reunited and I feel rather anxious and unsettled. What should I do?

She was going through a divorce and she decided to take some time away from us ... about a month and a half. Divorce papers have now been signed and we are seeing each other again, but I feel like I don't know if/when I should call her, if/when she should call me. Essentially, I don't know how to play it. We had a very good time with each other this weekend. I've missed her a lot and all I want to do is spend time with her. And yet, I am scared of being rejected because she may not be emotionally available yet. In need of a little guidance. Thanks.
