Hey Falc (())
I am so sorry this is happening to you. I know your heart is broken. I am a BW in R, btw.
Reading your posts, I see that that the gravity of what your wife has done and is doing to your marriage hasn't quite sunk in yet. It took a long time to sink in for me, too. In the early days, the infidelity is hard to really fathom for the depth of betrayal that it is. It is easy to fall into making false equivalencies between what the ws did/does and your own failings in the marriage, like being too controlling sometimes, or having a temper.
Especially when we are panicking about losing this precious thing that feels like the center of our whole universe, our mind is trying really hard to protect us from the fact that this person--OUR person who was going to always be there--has already destroyed the most precious parts of what we had together. We don't want to fathom that, so we go into a sort of denial.
Unfortunately, if we operate from that place of denial instead of a place of hard, hard honesty with ourselves, we enable further destruction of ourselves, and also completely sabotage any chance that those precious things that our M was built on might someday be rebuilt, with tremendous pain and effort.
To help you understand what I mean, I am going to give you a metaphor for what is happening to you right now. I want you to think about your current situation in terms of this metaphor.
You and your wife own a home together. You come home one day to find your wife using a sledgehammer to tear down the walls and ceiling of your house. You run to her in dismay and horror: "wife! what are you doing?!" She responds that she doesn't like the house any more. She complains that you were doing a bad job of taking care of the house. You didn't clean it enough, and made messes all the time. You spilled beer on the floor and now it's all sticky. Plus, the decorations aren't nice--you never let her pick out nice new things for the house. So lately, she's been looking around at the house and feeling miserable and trapped. She tells you all this while she is actively wrecking the place with this sledgehammer.
You follow her around as she continues to smash wall after wall, floors and ceilings and windows. You tell her you're so sorry that you've been making such a mess! You didn't know how important it was to her to get new decorations! You are willing to do whatever you can to help her feel happy and fulfilled in this house!
She shrugs and goes into another room and smashes some more things. Then she turns around and looks at you and tearfully asks you to stay in this smashed room so that she can go upstairs and smash some more, because she needs time and space to think if this is a house that she could ever really be happy in. She hugs you and kisses you and tells you she loves this house, she just doesn't know if she can live here any more.
You are freaking out because you don't want her to destroy the house. You love the house, and you love her, and you want to start fixing things. You tell her that, and she reminds you that you are definitely the one who ruined the house for her, and she isn't ready to let you start doing a better job taking care of the house yet, because she needs more time.
She tells you that maybe in a few hours you can come upstairs and you can talk about the house some more. She'll see how she feels. But maybe by then she'll be ready to start talking about how the two of you can make the house better. Then she walks out of the room, smashing things as she goes, leaving you in the middle of a pile of rubble.
You hear her smash her way up the stairs, and then you hear her demolishing the whole upstairs in the distance.
^ This is the situation you are in. This is the picture that outsiders to your situation who have been there can see. You are very close to it, and in shock and trauma, and can't see it entirely clearly. But this is what is happening to you.
Your wife isn't just "taking space," she is actively demolishing every precious thing you have with her, with each passing second that she carries on with this other man. And please be assured that carrying on they are.
So when you express concerns that if you act too harshly, or draw a line in the sand, that it may push her over the edge...what we can see that you cannot yet, is that she is already way, way, way over the edge. She has already demolished most of your house, including most of the foundation (honesty, trust). It is beyond repair now, the house you HAD with your wife. Pieces of ceiling are falling on your head. The floor is giving out from under you.
The house you had is already completely destroyed. It is in ruins. And you are standing in it, alone and in danger.
So, while you are wondering what "smart move" you can make to get HER to stop sledgehammering and come back to the room where you are, or if you should check on her to make sure a piece of drywall isn't about to jab her in the face, the rest of us can see that these are ultimately the completely wrong things to be wondering.
Because you are in a ruined, demolished marriage that SHE has ruined and is continuing to ruin. You may not have been the best husband, blah blah blah (very likely most of these complaints were very minor in her mind until she needed a reason to justify being unfaithful). But really, truly, nothing you did destroyed the marriage. SHE destroyed the marriage. And it IS destroyed--the marriage you HAD.
Given that reality, you only have one possible option to save YOURSELF right now. You cannot save her, you cannot save the marriage you HAD, you just can't. Period. She is sledgehammering, and has told you to leave her alone to keep at it.
You ONE option for self-preservation is to LEAVE the house. Right. Now.
It could collapse on you at any time. Get. Out.
If she is shouting threats at you as you try to leave, about how there will be no hope for the house if you do that, or she will make things really bad for, let yourself laugh at those comments a little bit, despite the horror of it all. The house will only be beyond repair if YOU leave?? Really?? LOOK AROUND, dude. She could "make this hard"?? Really??? Do you feel that she is currently making things easy??
You don't do the 180 to get them back. That is NOT what it is for. It is not a "show" you put on, to make them realize how strong and awesome you are.
You do the 180 to SAVE YOURSELF. And to remind YOURSELF how strong and awesome you are.
And sometimes, when you do that--when you run out of the house and brush the bits of paint and wood and drywall off yourself and find a nice, new place to stay with awesome, nice new people, and stop worrying about what the crazy person is doing to your old house, because you have already written off that loss--sometimes the crazy person will come to their senses, put down the sledgehammer, and run to your nice, new place, finally realizing that it was THEM who completely destroyed it all, and beg you to let them build a NEW house with you. Not fix the old house, that thing is F'ed. But maybe together, you can build something new, if they can make you believe that they have fixed the crazy that made them sledgehammer your whole old life.
But that is NOT the goal. That is just a remote possibility that, if it happens, you might really not actually want in the long run anyway.
The goal is to get out of the falling down house with the sledgehammer lunatic in it. She is no longer your wife, and there is nothing to fix.
I hope this helps you get a little clarity. I know it is so painful. And I am so sorry.
