WW Wife - Do I confront her?

[Matrix]

I found out about OM before I discovered this place or DB/DR. That evening I went down to the kitchen where my W was making my lunch for the next day.
A - We need to talk about [OM name]
W - What do you want to know
A - Is it serious?
W - It is for him I don't know for me.
A - Is it sexual
W - Yes
A - Is it going to continue?
W - Yes
W leaves and A starts weeping into his arms.

Andrew - Thank you for your response.

I can tell you for 100% certainty that if we were still living together, I would have confronted her immediately on the spot. There is no doubt about that. I don't know how she would have reacted, but I would have confronted without a doubt.

My problem here is that we are already separated. There are no consequences if I confront her, except me filing for D if she continues the A and I am not ready to do that.
