Brother, I've been thinking about your situation a lot and I want to share some things that I believe matter here. Right now you're getting words with no actions — that's not remorse, that's damage control.
1. Demand a complete written timeline. Tell her: "I need a complete written timeline — when it started, who he is, how many affairs there have been, what personal details about our life were shared, and what money was spent. This is a requirement for me to even consider staying, not a negotiation." If she leaves out his identity, she is choosing his anonymity over your healing. A genuinely remorseful spouse writes it without being begged. One who delays, minimizes, or protects him is still protecting the affair.
2. Expect the truth to come out in pieces — and don't accept it. First versions of the story are almost always incomplete. Every new lie you catch later resets the clock on your healing, and she needs to understand that.
3. Actions, not words. Real remorse looks like: full transparency (phone, passwords, location) offered without you asking, a written no-contact message to the guy that you watch her send, answering every question without anger or defensiveness, and getting into individual counseling to figure out why she did this. "I'm sorry, can we move on" is not remorse.
4. Get STD tested. Non-negotiable, regardless of what she claims happened.
5. See a lawyer — just to know your options. Knowledge isn't filing. You can't make a real decision from a position of ignorance and fear.
6. Once you learn who he is, find out if he has a wife or girlfriend. If he does, she deserves to know. She's the one person with equal stakes in this, and telling her kills the affair's secrecy for good. This is another reason his identity can't stay hidden.
7. Don't compete for your own wife. Don't rush to reconcile because you're scared of losing the marriage — the marriage as you knew it is already gone. Take months, not days, to decide anything.
8. Skip marriage counseling for now. It's worthless while she's still hiding things. She needs individual counseling first. You deserve your own too — this is trauma, and it's not weakness to treat it that way.
9. Take care of your body. Eat, sleep, hydrate, lift, walk. The first weeks are survival mode and your body will try to quit on you.
One last thing: you did nothing to cause this. Whatever problems the marriage had, she had a hundred honest options and chose betrayal. That's on her. I'm here whenever you need me — day or night.
