She said she was in love with him a few days ago. What does she say now?
My assumption based on memory posted here is that your wife still has deep "feelings" if not in love with other man, but she believes cheating is wrong, she is ashamed she cheated, she thinks you are OK but just not in love, she thinks that given the situation there could never be a "happily ever after" situation with other man, destroying too many lives, and therefore she is willing to really this time, despite her past failures, really try to repair this marriage. She is not overly committed, but she really very sincerely means it that she wants to try. If it doesn't start getting better, she may decide to divorce, but she won't cheat again. That is what she believes.
You also are not overly committed, just saying you will see. You both want it, but will go your separate ways if it doesn't.
Given that situation, you are putting yourself in easily avoidable obstacles of other man wife not knowing and your wife still working with him.
More important is the working together. They have feelings. It is temptation. It is a secret place, who would know? It likely will continue at some point if they see each other at work. Temptation is right in their faces. Reconciliation is tough, she will come into work and want to talk with him even more so because of how tough it will be reconciling at home. I am not saying her to quit or change. I am just saying that is how these things play out. It is not that complicated.
Even if she doesn't cheat, she sees him. Even if she wants to stop thinking about him, she can't, he is there, he is mentioned by others.
Now add in that his wife doesn't know. She is not calling/texting him all day, checking up on him. You threatened, but how will you find out. At first he won't "cheat," he will "talk" because she can see how upset she is. Teary eyed.
Can you see the obstacles? Even if she quit and other man's wife knew, it is not a slam dunk that you would reconcile, it still is iffy.
Add in that you both will "wait and see." Not saying that we will fight tooth and nail and never give up, we will keep working until our marriage is good. Just that we will do our best, if it fails, at least we tried. That sounds good, but look at the temptation and the obstacles.
Moving gears for a minute. I've been close enough with people who are highly sought-after by the opposite sex. Model/athlete types, or ultra wealthy and attractive enough. Married people. They are in temptation every day. There are opposite sex showing availability every day, some more overt than others, but every day. It only takes one bad day. When temptation is there every day, it only takes one weak moment.
This is somewhat similar situation your wife is in with seeing other man every day. If she had good boundaries, then she would have no problem. But she seems weak with avoiding temptation.
I understand your reasons completely, and your reasons are not without merit. All I'm saying is you can't expect ti win if you haven't set up the situation realistically to win. People do win against great odds, we love an underdog, but it doesn't turn out that way often.
