Let me correct something as I thought that EM was extra material affair. My wife had an affair. Emotional and physical.
EA = Emotional Affair
PA = Physical Affair
Overall I am in a state of fear.
CIST, please don't let your fear govern your actions. It's a mistake that many of us BS's have made, including myself, and suffered because of it. At the moment, your WW is not the woman you knew, but someone else in your wife's body, and your M effectively ended when she chose to have an A with someone else. Now, you could rebuild a NEW M with her, but it's a long tough road to creating one that's you both *want* to be a part of, rather than one you feel that you *have* to be a part of because of other commitments (e.g. children).
We have children and each of them would be devastated should I not find a way to hold on and work through this.
How old are your children?
About calling his wife to verify his story, I would leave her the second I found out that he lied to me about telling his wife so I am afraid to follow up on that.
I think you are letting your fear govern your actions again. I'll be you also told yourself before that you'd leave if your W had an A, right? Yet, here you are.
The right thing to do is to call the OMW and confirm the story. Don't let your fear stop you from doing the right thing.
Not to mention my wife would flip out at the thought of me calling his wife.
Let me help you with that - your W WILL flip out. But that's not your fault - YOU didn't choose for her to have an A. That was entirely her choice. And here's the thing, CIST - women don't respect men that are ruled by their fears. You're not going to earning your W's respect by not contacting the OMW out of fear that she'll get upset. You WILL earn her respect by standing up for your M.
I know that if I demanded my wife leave her job she would not do it so what choice do I have in that matter. If I demand it that she leave we are headed for divorce anyway. Because of the kids and the harm that this would do to them I feel as if I am trapped.
That's your fear speaking again.
Again, your M effectively ended the moment she chose to have an A. What your fear is leading you to do is to make choices that effectively allow your M to coast on for awhile. What you should be doing is make those choices that either (1) end the M decisively and properly, or (2) rebuild a newer, better M between the two of you.
Accepting a situation where your WW continues to work with the OM meets neither (1) or (2) above. While you may not demand that your WW leave her job, you can make it very clear that it's an unacceptable situation that she has to resolve by a specific agreed time.
And finally, if you do want to save your M, don't ever *threaten* exposure, to try to bully your WW into doing what you want. Exposure is a tool that should be used to break up As, not bully your spouse. And if you have to do it, just do it without warning, indicating to the parties that you're exposing to that you want to save your M and you'd like their help.
