Venting: We had the ENM conversation in the late '60s or early '70s. We agreed that we couldn't see it working short, medium, or long term for us at all. Then, 4 decades later. My W let ow convince her she had evolved to a level at which she could love 2 people simultaneously. I hadn't evolved to that level, so it was best to keep me in the dark over my W's Stranger in a Strange Land growth.
W was going to split her time. As far as I can make out, we were both going to get W 12 hours a day on average. That meant 12 waking hours with ow, the rest for me. IDK what was going to be done about travel hours. End vent. (W eventually saw she had sold herself out and decided to end the A>)
Your W has put you into a very difficult position. Alas, it's up to you to get yourself out of it. You have to choose between accepting your W's decision to open your M or D.
Here's the thing that stands out to me:
If you accept what you don't want, you doom yourself to living every day in pain, and you doom yourself to letting your W choose D whenever she wants to.
If you choose D, you separate yourself from the source of your pain, and that opens up healing as an option.
IOW, you give yourself an opportunity to lead a good life if you force your W to choose between you and om. You make a good life much less possible for you - and for your W, too, probably - if you give in to your W's ultimatum.
And don't forget: if you issue your own ultimatum, your W may wake up and choose you.
Your choice really isn't lose-lose for you. You've lost your W already. An ultimatum - if you're ready to dump your W if she chooses om - at least offers you a chance to win a good life, with or without your W. But if you force her to choose, and she chooses om, you need to D.

My spidey sense was energized by the phrase 'failed M'. I don't know what happened in your first M, but if this one ends in D soon, it's because your W failed. You didn't fail. Your M didn't fail. Your W failed.

I think I comprehend some of the pain you're experiencing. I don't know if your W is having sex with this guy now, but what she says is tantamount to cheating.
There's no way around this, though: you often have to risking ending the M to save it.

It is sometimes possible to end an A with a co-worker without quitting the job, if contact can be limited to true professional obligations. I don't think that's possible if the aps work together closely. In my experience, good project work has an intimacy that can destroy boundaries. Remember: in some ways the creativity needed to reach project goals is at least almost sexual.
Your W may have to choose between you and her job - but if she chooses her job, what good is she for you? She needs to choose you without reservation. If she doesn't do that, IMO she's a poor bet for the long term.
Why would you want to stay with someone who doesn't put staying with you above going with any other person? How does that help you make a good life?

And if this pargon of a co-worker is in a committed relationship, I hope you find whatever it takes to inform OBS of the guy's commitment to your W.
Forced to choose, he may end the A. That might give your W the separation she needs to change herself from cheater to good partner. No matter what, though, your best bet is to end your relationship unless your W commits to changing from cheater to good partner.

Again, I know the pain is excruciating. The problem is that the pain starts to end only if you do what you need to do to end it. Healing isn't quick by any means, but healing is eminently doable.
