Walk away Wife having affair

[Hurt06]

Yes I have DR and applying a lot of the steps. I am trying but do slip occassioally.

Found secret love emails and pictures by accident and its very clearly a teenage type relationship....very childish sending her constant divorce referrals, love emails etc.

OM's wife is divorcing him and keeps me posted on her end. He is couching my wife to talk to attorney and file as soon as she can. She is prevented from filing for another few months due to a legal technicality so she can't and he has coached her on this. Obviously I have asked her if she is talking to an attorney and she says no but everything that comes out of her mouth is a lie anyway so I have to assume she is. He is also setting up his home and sending my wife demographics about how great is is to raise kids in his city. All very heartbreaking.

Basically The affair has been going on for more than six months and she is refusing to stop. My job requires me to be gone 3-5 nights a week so she gets free reign while I am gone with the only restriction is our three kids. The man has come to my house while the kids are in school and I'm outa town and I'm unsure how to stop this. I guess the only way it gets any worse is if she gets pregnant. I'm really at a loss about what to do and she is acting completely like a late 30's out of control teenager.

What all details do I need to lay out so that I can get some guidance?

Thanks for the help.
