I'm sure it's possible. I wouldn't be surprised. How does this play into what I should do?
How could it NOT?
Legally, financially, emotionally, medically, the dynamics are all very different. And while you still want to do 180s, GAL, and some of the other DB basics, how "aloof" I would recommend you be in responding to her would be affected by what she was doing, and with whom.
Someone seriously confused, and/or responding to legitimate marital complaints, needs WOOING. Someone in an affair, and LYING about it to you . . . eh, not so much.
