Hi Huddy, try not to read too much into 'unnecessary' contact from your W. She may just have thought of it and wanted to deal with it there and then.
I think we do ourselves a huge disservice if we watch and wait for our spouse to get their heads out of the fog. They may do so soon, it may take one year, five or never - we just don't know.
IMHO, it was your W's choice to 'end' your M. If she regrets her choice, she will clearly let you know for sure. Until or unless that happens, I would live your life as if she isn't coming back and coparent as best you can.
From what you post, she may (or may not) have had a tiny peek out and ducked back in, but her behaviour when she came around says something too. I wouldn't analyse every interaction - it's no way to live your own life.
I think you're focusing too much on her and need to regroup and detach - it's a mini 2x4 and well meant my friend. X
