First, I’m very sorry that you find yourself in this situation. It’s a nightmare and we all know what it’s like. You can take some tangible steps right now to get your self clear of this moral morass.
You’ve gotten a lot of advice already, but some things to consider in addition to the VAR (you need a VAR to keep on your person anyway, so best to go get a few).
1. You’re doing the pick me dance. Stop doing that, flip the script and implement the 180 on your WW. It’s hard, yes, but necessary. She won’t respond to your pleas or needy attention. This is who your wife is, and while that’s very difficult to accept, the sooner you do accept it, the better. The way to deal with someone like this, man or woman, is to implement the 180 and take the steps outlined below.
2. See an attorney and get out in front of her on divorce. Seems counterintuitive, but you can make this real for her by putting a separation agreement in front of her.
Then — if she doesn’t want to separate — say “Then I need you to do these things — all of them. Not up for debate. Take it or leave it. The whole package.”
Here’s the non-negotiable package you offer if she wants to remain married:
1. She provides you with a documented NC text and email to her. Proves she has deleted social media contact with the OM (OMs).
2. Gives you a detailed day by day WRITTEN timeline of her infidelity. Make her write it down in a detail. No more Reader's Digest version, no more of you having to piece it together like a makeshift quilt. Make her detail day by day and if you need it hour by hour. "I don't remember" and "I don't know" are LIES. It will be harder for her to lie to a blank page. Tell her you don't want him wasting your time with a bunch of superfluous nonsense like "I never meant to hurt you" "this wasn't about you" "it just happened" -- Just the facts.
3. Turns her phone and social media accounts over to you for examination and retrieval software (Fonelab is the software to get, and it will also retrieve information from iCloud).
4. Agrees to a polygraph measuring the veracity of the written timeline. This is absolutely vital. Don't let her weasel his way out of this. This is a tool of psychic pressure -- your BEST tool -- for getting the truth. No debating about whether polys are accurate etc. It's "do this or f*ck off."
5. Reads and begins to immediately implement her own documented written plan from the book How To Help Your Spouse Heal from Your Affair.
6. Takes a documented full STD panel to show she’s disease free. You should also do this IMMEDIATELY for your own safety.
7. Do not agree to couples counseling with him. She must enroll in IC with a betrayal trauma specialist (this is important so pay attention to therapist background), and same for you. Ideally it would be two IC’s who work together in a practice and each focuses on betrayal trauma.
None of that will decide whether you R or D. It will just provide transparency and a way for you to begin making informed decisions.
