do I keep things the same or try and reel her in with quality time between us with signs of love/affection peppered in?
I think you need to let her lead with the R for now. If she invites you on a date with her, or if she begins to give you some affection, then you'll know she's getting to a better place. Since she's not ready to move back just yet, I think you need to be careful about pursuing. Take it slow and easy.
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!
