The jump to "Piecing" doesn't change one of the ground rules that got you here...
Let her set the pace in which she is willing to work on M. This early in the stage, she is still sitting on the fence when it comes to how secure she feels M will be better. So let the scorecard go / let go of your expectations of what she should be doin in M for now. In "piecing" you need the find the delicate balance between making R feel good and safe and starting to work on issues, until she can feel comfortable that the issues can be worked on without the R going bad. She still needs convincing the old patterns are truly broken and until then she will still have times of distancing because of her apprehension, so it will still take lotsa patience on your end.
