Welcome to SI PBST2. Very sorry you find yourself here. What you are discovering is that your wife is regretting that she has been caught. She is not truly remorseful. She is showing some positive signs, but truly remorseful...no. How do I know? She wouldn't be complaining about having complete transparency for one. There are no more secrets. Even between her and a friend. That friend may not be a friend to your marriage. You do not know. In a health marriage, complete transparency happens naturally. I have access to everything of my wife's in case of anything were ever to happen. And I mean everything. It's not even something we discussed. It just happens. (I'm not a BS or WS, but rather a betrayed child, now 40, and a long story as to why I'm on SI) She is also now showing true remorse with her sadness comments. Sorry, she's the one that fucked up. She has to heal both you first and herself. That's how this remorse thing works.
Having her maintain contact with OM, even in a working environment is going to be damn near impossible for you. Every time she talks to him/sees him, you yourself will not be at ease. There is not amount of her reassuring you will help with that. This is why people must have NC (no contact) with their AP's. Have you brought up the possibility of her finding another job? If she truly wants to R, she should be looking. That said, with the phone call she made to him...well she's already proven that she's a liar. I wouldn't believe her for a second. I would be more apt that since they are in constant contact they took the A underground. It's up to her to prove to you that they didn't by complete transparency, finding a new job, looking after your well being, etc.
There's no doubt she's still in a fog from the A and IMO most likely still involved in the A. What about her AP's wife? She needs to know asap. The more people that know, the less chance the A has of going underground and carrying on.

Also make her read Not Just Friends and How to Make Your Partner Heal After the Affair.
Gently here, have you both been tested for STD's? Unpleasant experience but is a must. You would be surprised at how many times in these forums the BS found out later that there were STD's. In most affairs no protection is used even if they swear up and down that they did. And even then condoms to protect against HPV or herpes.
Next up, mandatory IC for your wife. She needs to get to the bottom of how she thought this was acceptable to her to do this to you and your family. This is not your fault. She is seriously broken in some way and she needs to figure out what that is. Not the excuses/reasons that the marriage was on the rocks or whatever you may or may not have been doing. That's all bullshit.
Keep reading. Keep posting. Sorry you are here, but we are here for you.
