Thanks AnotherStander, that makes a lot of sense - to tell her how I feel, but ultimately the decision is hers.
On whether or not she's having an A, emotional or otherwise, how or should I try to find out?
I've asked her a couple of times and she vehemently denies there's OM. She has mentioned potential greener pastures for both of us out there, so there's definitely at least an imaginary ideal partner that's "more like her" out there in her mind.
The reason I ask is because although I should be detaching, how hard I come down with tough love on a wayward wife as Sandi points out is different from a WAW without OM.
For instance we're still currently in the same bed, but if I knew for sure there's an A, then I would insist that she move out of the MBR.
How do I get to the bottom of this without snooping?
