Wife wont admit to affair, its driving me nuts! 2

[Morbo]

So, been mulling things over a few weeks.
I'm pretty happy in general, pretty much over W, doing decent NC.

Still feel in limbo because W is not interested in filing for D and is still unsure/whatever bout everything. I'm done with it anyway and not interested .
So I emailed her yesterday to say that I was finished, we should discuss filing for D and
that we should now be separated but to all intents, single. Short replies to and fro but no real agreement from her.

So, next day, I get an email from her saying she wants to go to counselling. This is the first time ever she has said this.
I replied non committaly and said I'd think about it, said we'd maybe talk when she comes back from her holiday at end of feb. She

Hmm, what to do? She seems genuine.
