Question - is she acting like this alien as long as the AP is in picture or does that not correlate to anything. Just curious. I know that going to marriage counseling is futile while the AP is in the picture.
Honestly it depends on HOW the affair will ultimately end. WW behavior can go on long after the affair is over.
You are making yourself the better choice...all you can do, in that regard...and YOU ARE DOING IT.
