Doc,
First, I'm so sorry for this latest info.
When you said:
"If I was fucking another girl, I couldn’t imagine badmouthing my wife to everyone in my life while being sweet to her face. I just have way too much respect for her—we’ve been partners for 17 years and we’re married with children. She’s too important to me to shit all over her.She felt none of that for me. She was done with me and this affair was her farewell to our relationship. And then in the eleventh hour, just before severing from me entirely, she was smashed with regret. Her perspective changed and now she loves and respects me again.
It’s a truth too horrible for her to admit to, so she can no longer navigate our conversations without losing all her self-respect. She needs to maintain the idea that the affair was just some fun on the side or else she won’t be able to look herself in the mirror."
As you said, you respect her too much to have badmouthed her to others even if you were having an affair.
The sad cold truth is that she does not respect you enough to not do that as she DID that and she did it a lot to many different people. She wasn't just upset and popped off to someone. No, that's the way she was for a long time. It shows who and what she really is. As always, it's actions.
Now, with the latter part of your quote above, she is NOT staying or trying to reconcile for you for the right reason(s).
As you said in a part I didn't include, she's lost so much and she doesn't want to lose you too. She's trying to hold onto to something and that's you since she's lost friends, the AP, the PTA, her self-respect to many others.
In some way, she won't look as "bad" to others if you stay with her. Is that the only reason she wants to stay with you? No, I don't think so, but I think it factors into this, into what she's doing.
It's rarely just one thing. Things are made up of many different things, like a big stew with many ingredients, it isn't just one thing.
She's lost so much and she doesn't want to lose you too. Why? Many reasons, she knows you, she knows that you're a good man, she's counting on that, counting on you being there for her. I'd worry that she'd leave you like 4 years down the road when she's picked herself up off the ground and healed a lot more than she has now.
For a couple to reconcile, both partners have to be all in and she's not. I get it, she might become all in down the road.
Obviously I don't know you and you're an intelligent person but you really need to think in terms of how long you'll wait or give her to become all in.
I'm not saying to give her a few months and then go as that's not realistic, we all know that.
But, if you still think and feel this way about her and you still think and feel she's not owning up to what she really thought about you and your relationship a year from now or two years from now, you'll need to pull the plug.
Why? Time flies by and so many folks say things like "I wish I would have gotten out years ago" especially knowing what I know now.
I get you want to try and I applaud that. Don't just let time fly by and all of a sudden it's 2028 and things still aren't the way the should be between the two of you.
Don't let her be disingenuous about this reconciliation.
If she won't or can't admit this to herself and to you, it's not going to work.
There seems to be many things she "wants" from you and the relationship, like a safe landing spot for her cruel behavior, someone to help her, be by her side, make her look better to others, help her from being completely alone due to what her actions have done to her as they have consequences and she doesn't like them so she's grasping at what she can right now and that's you, your relationship.
This isn't what you want from the relationship of course, you want the right things, real love, a partner in every sense of the word, you want to be wanted the way you want her and she doesn't want you that way (not right now at least and she hasn't for quite awhile either).
I don't want to see you end up in a transactional relationship with her years from now.
When my dad divorced my mom, due to her cheating, she was so mad, she told him "you can't do that!" and yes she knew he could. She wasn't talking about that. What she was mad about was losing her lifestyle, her nice house in the nice subdivision, her staying at home, doing things with her girlfriends like playing Bunco, going to lunch and the spa with them. She loved the look of our little "happy" family. THAT meant something to her. She cared about the marriage for much different reasons than my father did.
No, I'm not saying this is exactly like your situation, I can't say that as I don't know. I'm just saying this about my parents as an example of one wanting to stay in the relationship for the right reasons and one not wanting to stay for the right reasons.
I'm sure the details and reasons are different for your wife and you compared to my dad, but there are similarities even though the details are different.
Your wife isn't all in and she wants different things from you and the marriage than you want from her and the marriage.
That bridge HAS to be crossed before the two of you have any chance of reconciling happily.
The worst choice folks can make is to straddle the fence and just bob along where the currents of life take them. It's OK to do that for a while, but please don't let that become the rest of your life OP. Now, I don't think you will, not from what you've written.
You want it to work out, as long as it's right and for the right reasons so hold onto that, stick to it and at some point put a time limit on it so you're not still just bobbing along in the raft without an oar. At some point you need to stick an oar into the water and guide yourself to where you need to be and want to be. You might want to head north, but if it's blocked (by say a spouse who isn't on the same page as you) then you might need to change your course and move along in a different direction.
Good luck to you, I wish you well. I want you to be happy, whether that's in your marriage or not.
