She wanted me to be home. I think she was afraid of her fantasy and reality clashing. I would have prevented it if I was home.
I hope you can see how terrible this dynamic is. That you must be there, otherwise she is too weak, too irresistible to overcome her desire for another man.
She has to be a fully adult with self control and accountability.
You want to be her husband, not her father, and worse yet, her warden.
my soulmate ... each others 'loves of our lives'.
Too much pressure for that. What does it even mean, "soulmates," "loves of our lives?" It was a two-year inappropriate relationship the main part secret from you. I would just say I don't believe in soulmates and loves of our lives, except what we make it through ACTIONS. Too much to deal with infidelity, leaving the marriage, and trying to navigate the whole soulmates stuff, too. I'm no statistician, but I don't see many soulmates reconcile well. Maybe you can just be spouses who love each other and share a life together.
I'm glad you were able to retrieve enough of the texts to see the big picture, to know basically what it was. That is huge for eventually moving forward one way or another. I'm glad it was basically what she said.
I think this marriage ended when his dick made contact.
I put this up there with the soulmates stuff. Her body can be cleaned with warm water and soap. She could have been date-raped, probably not, almost definitely not, but what if she had been raped forcibly? Think this through, is her physical contact the problem, or her willingness? Is it not a problem on intention and fidelity than a physical problem. The physical is easier to visualize than her intentions and loyalty. Think this over a bit.
You have some great ideas and some terrible ones. This is a roller coaster, especially now early on. Try to moderate the highs and the lows. Throw out any extreme actions and words, table them for a while before doing them.
I so much understand the wanting to hurt her the way she hurt you. That was my main feeling afterward. My wife and I reconciled. I am not an expert, just one guy's opinion based on my own experiences and observations. So:
1. The sex with her girlfriend is a terrible idea, you won't even enjoy it except for the moment, the next minute you won't be in any better position, you'll feel good when you give your wife the big "FU" then you'll be in a new spot, even worse than before. I didn't do it, but I've spoken with enough men who did.
2. The notch in the wedding band or engagement ring is a Scarlet A, the permanence of her behaviors are in her head and yours, it will fade away, like a scar, like any pain, like any trauma. Why would you want to make a permanent physical mark to memorialize it? You trashed the affair furniture, clothes, etc., so why trash the ring. Look at it this way, the ring was a symbol of your marriage, not the symbol of her affair.
3. If you want to get a new ring and wedding band, new vows, new marriage, new start, that is all good, but the permanence of holding onto the trauma of the affair - don't do that. Do it now, as long as you want, but don't plan for future pain as a symbol forever.
This is a long process, 2-5 years, and how far are you on the let's say 2.5-year process now? I am psychic, and I will help you out with one prediction, and here is what will happen - you will either stay with her, or you will not. I guarantee it. If you are undecided, act in such a way that will help you in both possible futures.
