Id also like to know did you feel her building follicles? See an ovulation? When was her last shed?

Also, you should not be housing the pair together 24/7. While it is ok for short breeding visits, it can be stressful on your animals (who are not natually social animals) over long periods of time. The curled up together when not showing an interest in breeding is usually I sign of competition for what they consider the best "spot". If I were you Id move the male out asap (moving the female will not help your breeding efforts) and only introduce him for a few days at a time if you think she didnt take yet.
