IMHO, you did fine, especially considering the short notice she gave.
I got the impression that she sees moving back to reconcile as being the less attractive option.
If she really misses her children, she'll be over more often to see them these next two weeks. However, if she comes over and doesn't spend quality time with them, then I tend to think she's missing her place more than the family.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
