I’m so sorry.
It not about you.
The others are correct. Your wife is very likely in limerence with this man.
Go to you tube and look up "what is limerence"
But don’t get sucked down a rabbit hole of thinking this is some temporary insanity or some kind of temporary sickness.
This cannot be cured.
Yours is even worse as you are also dealing with the phenomenon known as "lost loves".
I say these dry explanations to tell you that it is not your fault.
These are very dangerous things that are more common than you think.
She is doing terrible things to you not because she hates you.
She is doing these things because she loves him.
He is all that matters. You are collateral damage.
Under the spell of limerence you should be happy for her. You should want for her to be happy.
Any resistance makes you the enemy.
You can’t fight this.
This is already very dangerous.
You need to move as fast as possible to separate your self from her.
You have no choice.
You have to let her have her new fantasy life.
The more you resist the stronger her feelings for him become.
I know it’s hard to think of the person you love as your greatest enemy but that is unfortunately your new reality.
Don’t fight with her, argue with her, try to persuade her. You may be able to get your lawyer to set up all communication to go through them.
You need to disappear completely from her life.
She needs to be alone with him in her new world.
But don’t expect her to come back any time soon.
She very likely will start to regret her decisions but because she has thrown away so much she will work hard to try and make it work with him.
Another term known as "sunk cost phalacy"
This is a big reason this is a contender for the most dangerous type of affair.
This could take years to work out.
You can’t wait.
Now there is a small chance that strong immediate action could bring her back.
But even if that happens you can’t fully trust her after what she did.
You have no choice but to get permanent legal protections for your assets.
Even if that means divorce and you start dating again.
I highly recommend you read the book "not just friends"
In the beginning of the book they reference this epidemic.
Find the footnotes for this section in the book and that will reference researcher Nancy Kalish, I think that’s her name. She has a whole website
Dedicated to this subject.
She believed that this needs to be strongly advertised nationally that people need to stay away from the ex’s on social media and in life.
I mostly wanted to second everyone that you need to move in quickly and protect your self.
But I also wanted to let you know that this is a legitimate real phenomenon so don’t make it as much about you.
It’s not your fault. Your wife opened a bad door she should not have opened.
She got herself in over her head.
I’m so sorry. My heart breaks for you.
