Welcome to the club that no one ever thought they would be a member of. You will always wonder if you know everything.
I strongly recommend you reach out to her husband and let him know what's going on. He has a right to know where he stands in his relationship. I waited 5 months before reaching out to the wife of my wife's AP and I regret every day I waited. It wasn't my place to decide what she gets to know about her relationship
The anger the sadness the loneliness Etc will be there for a long time. I demanded my wife start IC to figure out what was broken and or missing inside her that let her gamble a 27-year marriage. The fact is people cheat simply because they are selfish and they want to. They enjoy the dopamine hits they enjoy the attention. For my wife it made her feel like she still "had it" even though she was closing in on 50 years old
The mistake I made was demanding MC right away and in hindsight I wish I had waited several months till my head was clear and then decide whether or not I wanted to save the marriage
An affair causes permanent changes in a relationship. Reality is, an affair is a possibility from day one through every day of a relationship. No relationship is affair proof. Things are well between us but I will never ever again implicitly trust her. My ability to do so has been permanently destroyed and were I to find out she was messing around again I would just shrug and go about my day.
ETA: a permanent change that happened in our relationship is my wife no longer goes out with coworkers after work. I have never ever been okay with coworkers going out and drinking and socializing together, that is just a recipe for disaster because most affairs start at work.
If you want to make sure he is not around her you could make the demand that he finds another job. That is something I wanted to do but my wife's job provides the health insurance for the family so as a father of three boys I had to suck it up and deal with it and every morning when she left for work it was so hard because I knew they were both in the same building and of course my thoughts went to both of them figuring out a way to just be more discreet. I found out on a Thursday and 10:00 a.m. Monday morning I went to my wife's work, she works at a school. I walked into the office and asked the secretary to call down the police officer that works in the school, he was the AP. He walked in all smiles and whatnot and said how can I help you and I said is there somewhere we can talk
We walked out into the foyer and I said my name is and I am so-and-so's husband, I thought we should meet. The smile disappeared and he put his hand out and said I owe you an apology and I just waved him off and said I'm not here for an apology. It was about a 20 minute one-sided conversation and it wasn't anger and accusations because I was nothing but a shell of a man at that point, I was completely gutted
And I said what I said in hopes that it would give him pause and change his ways but turns out it was futile because after my wife he moved on to the social worker at the school. After chatting with his wife it turns out he has done this before and he will never change because she keeps taking him back
