JSpaceman,
I am sorry that you had cause to look for a forum like this, but I am glad that you found it. It will enable you tap into the advice and thoughts of many people (the forum has more than sixty thousand members) who have experienced infidelity, and who who know what works and does not work in its aftermath.
When I read this line in your original post, it rang alarm bells for me:
She also seems sincere in wanting to reconcile our marriage. As part of that she's been discussing everything from offering some sort of "hall pass", to a break in our marriage for me to recover, to even an open relationship.
All of those options sound designed to benefit her, and a couple of them will offer her ample opportunity to continue her affair.
(1) Offering you a 'hall pass': Think objectively about who really benefits from that. You have no desire to have sex with anyone else, so where will the benefit be for you in doing that? However, if you take her up on it, it means you cannot hold anything against her for her infidelity. So she will be the major beneficiary.
(2) Taking a break from the marriage 'for you to recover': This is a variation on a cheating spouse suggesting a trial separation so that they can 'find themselves'. Real life shows that what such breaks are really designed for is to enable the cheating spouse to continue their affair in the absence of the person they betrayed.
Think about it: you did not request such a break, she offered it, and dressed it up as some kind of act of empathy or compassion. How is being apart from her going to help you recover? Would it not be more beneficial for her to stay and prove to you that she is doing the work and taking the steps to prove she can be trusted. The break she has suggested lets her off the hook, and it is clear that she will use the space to continue her affair, while leaving you to sort yourself out. How compassionate is that?
(3) An open marriage: Wow...So she is offering you a solution that allows her to keep you on a string, and retain the security of the marriage, while pursuing her affair with this other man. Who is the major beneficiary of such an arrangement, you or her? It will be her, which is why she suggested it.
Apologies if I sound cynical, but infidelity does that to a person.
Your wife's mind-set is offering only options that will further damage or nullify what is left of the marriage. None of the above are about repelling an intruder - her affair partner - and repairing the marriage by breaking contact and her making an effort to reconnect with you.
You seem to have sensed this yourself, as in a latter post your wrote:
And though she seems to be trying to hold on to the marriage, she's letting me know she doesn't really have a leg to stand on here, so it's kind of my ultimate decision.
There is a difference between trying to hold onto a marriage, and actively working to repair the damage she has caused to it. And holding onto it is about retaining a possession for herself.
She needs to be actively reaching out to you provide what you need, not standing back and saying "Well, it's up to you...I can't do anything". Where is the commitment to holding up her end of the bargain? The only options she is offering are dissolutions of the principles of the marriage that stop short of an actual divorce.
I am sorry if this sounds negative, but my aim is to prevent you from being taken for a ride here.
These two statements are contradictory:
...if her word is to believed, she broke it off with him ("let's just be friends") that same day she left Austin, and the day it all went down outside the shower.
...she still wants this person in her life. She feels bad that he can't rent our house now, so she wants to help him find a new place, or even to help him pay for the deposit on a different place.
What does 'broke it off with him' mean if she wants to maintain her relationship with him? When it comes to affairs, experience of real life shows that the affair and the relationship is either 'on' or 'off'. There is no middle-ground of 'let's be friends'. If she is actively maintaining her relationship with that man, then she broke off nothing at all.
Why does she feel bad for him an any way, shape, or form? He is clearly a leech that is using her for free sex and financial support, and the kind of man who is fine with sleeping with other men's wives. And your wife appears to have put him on a pedestal, and to have focused her empathy and sympathy on him.
That is ass backwards.
She should be focusing her support on you, and letting the scavenger she idolises scamper off to find another source of sex and money.
You should start checking any joint credit cards or bank accounts to see how much money she may have already spent on him or given him. And if you have any joint credit cards, cancel them immediately. Why should she have the ability to give him your money?
She feels like this person is in her life for a reason, and that reason is to help him.
That statement illustrates just how deluded she is. She is clearly in the land of fairies and unicorns that many waywards create for themselves, where cheating and betrayal becomes re-cast as noble and positive. It must be 'destiny'. It must be 'fate'. It must be 'the will of the Gods'.
Or maybe it is just a deluded woman having a mid-life crisis, and demolishing her life to become a source of sex and financial support for someone who seems to be the prime beneficiary of the arrangement, and who is offering very little in return.
It is essentially a parasitic relationship, not the karmic 'meant to be' nonsense that your wife is drugging herself with. She has picked up a freeloader, who will take all the sex and money she cares to throw at him to 'help' him, and then move on. The only person who cannot see that is her.
Start to separate your finances, and consult a lawyer about what a divorce would look like. Doing these things does not mean your are going to get divorced, but you need to start protecting yourself from the silly delusions your wife is filling her head with.
And make her a counter-offer by way of available options: She cuts all contact with her affair partner and focuses her mind on helping you.
