CB, take a look at the stages of change that I posted in Bea's thread "New light on MLC":

It is likely that your W is still in the process of change (ie. transition / MLC)... like that wasn't stating the obvious... grin

That said, your feeling like things are a bit like the months prior to BD could be bang on, which could mean that your W is making an adjustment.

Until she finds her peace, her rhythm, her pattern... she will likely do this.

Do your best to stay out of her way (because of possible MLC spew) and keep encouraging and supporting positive changes as she moves along, without offering help. Even if that means just saying or doing nothing.
