Update
I told my wife the whole deal yesterday and things have been tough since. Not like I was surprised about the reaction, but it hurt both of us more than I expected it to.
My wife is still a bit all over the place emotionally. I've remained steadfast that I view my commitments and vows to her as sacred, and that those will not change so long as we are still together. That I would protect, provide, and be faithful so long as we were an item.
She views this as the first step to a full divorce, which is technically true, to be fair. She's threatened the actual divorce a few times (since last night), and also said she would allow me the "financial divorce"... she keeps going back and forth. (this is why I hadn't posted an update until now). Many times she's told me she does not want my money if we separate, and many times I've told her that this is asking me to trust a version of her that hates me - to not take free money. This is a back-and-forth commentary. Keep in mind that
my wife has lied to me before, and is still actively on the instagram account she promised to delete 3x over now (I've verified nothing shady is happening, but it is still a lie that she's promised to correct yet actively violates. she doesn't know that I know).
I've told her that if she wants to leave - if she wants to end the relationship 100%, full divorce, no commitments, that she is and always has been welcome to do so. But that
she would have to be the one to walk away, and that
she would have to be the one who separates our family. Is that a little fvcked up, maybe - but I'm genuinely not trying to change anything in our relationship except to continue working on it the way I have been for the last year. It's a semantics thing; I viewed my wife as my life partner since before I proposed - I knew I wanted to be with her for the rest of my life. Getting legally married did not change how I viewed her or my commitment to her, it was just a thing I did because that's what people do (I was not thinking for myself at this time. Hence naïve commentary).
I will consider her to be my wife so long as we are together; the state is the only member of this marriage I'm trying to be rid of.
I own my role in this. I know what I'm asking for is neither fair nor normal. As I've said before, I made some very naïve choices when I was young, and not preparing for the possible outcome of 50% alimony for life - is one of them I'm paying for now. If there was another option that actually held up in court, I'd be all over that like white on rice.
As of right now, the cards are in my wife's hands. If she wants to be with me, I've invited her do so so in every manner of ways - and these are the terms. If she doesn't want to be with me, then that is her choice - but I'm not going to end it for her.
I am deeply saddened by the possible ending of a relationship with my best friend and time spent with my daughter, but I feel I have no choice but to do this and have accepted both outcomes.
I will try to keep this thread updated as things develop. Thank you to everyone for your input and experiences; you have all helped me through some of the toughest times in my life.
