I’m so sorry and so outraged on your and your children’s behalf, OxfordComma. You’ve gotten a lot of good advise already, so I won’t belabor it.
I will say this: this is not a case where you can start thinking in the normal terms about managing your trauma and deciding how to proceed in your relationship with your wife. You have a sexual predator and a very sadly damaged young man living around your children, and that has to take priority here. You HAVE to protect your children first and get those two away from them immediately.
Your WS prioritized "parenting" of this young man over her own children, while also becoming sexually involved with him. The level of mental disorder here is staggering. I’m sorry, but you should not be thinking about reconciliation at this point. You are absolutely in urgent crisis management right now. Regrettably, this young man is not safe for your children to be around, but neither is your WS. At the very least, she is a grave emotional danger to your children. But at worst, they both represent an extreme emotional and physical danger to your kids.
There is no way of knowing the extent of the AP’s issues, so yes, you absolutely have to consider your safety, your children’s safety and the safety of everyone in your household. You don’t have the luxury of time to get control of that part of this horrific situation. It has to be done immediately.
You need to expose for everyone’s safety. No one who is ignorant can protect themselves.
You need to have legal and mental health support as quickly as possible. Like today.
Finally, I’m sorry, but even using the word reconciliation in this thread in light of the realities of this situation shows that you are not truly understanding what has happened. We all have to realize that our M is dead when we discover infidelity, but you, dear friend, have discovered infidelity AND that your wife is capable of extremely depraved and twisted predation on a young man who came to your home for PARENTAL support. Your wife has had sex with someone that she had calling her "mom." Your wife simultaneously mothers him and sleeps with him. Your wife has brought a potentially dangerous situation into your home. She has held this horribly unhealthy connection above her connection to her own children and her marriage and her respect for your lives, your family, your beliefs, even her own parents’ well-being.
This is NOT a situation where you should in any way be wondering about whether she’d be open to R. To even have that thought while you still don’t have any inkling of the extent of what has happened here and while you are so recently aware of the existence of this situation at all must be considered an extremely trauma-induced and unhealthy thought process.
Please put that out of your mind right now and focus on removing your kids and yourself from danger. You may very likely be their ONLY stable parent for the foreseeable future. You HAVE to focus on your own well-being on all fronts so that you can be there for them and support them through what you must realize is going to be a traumatizing experience for them like few others. There is no avoiding this now that your wife has chosen this path.
As a final note, it is quite possible that your wife has committed illegal acts here. She has certainly committed heinous and immoral acts. You really need to consider carefully and distance yourself clearly from her actions. Do this to protect yourself and your family from the fallout that lies ahead.
I’m so sorry that this has happened to you. None of us asks for this or deserves it, but we have no choice to be paralyzed when children are involved.
I wish you strength and clarity, OxfordComma. This is a great place to come for support.
