Good morning, Gemmy.
Who says you're "supposed" to do anything? I don't think there's any reason you "should" feel grateful or appreciative of her efforts to own and fix her shit. You're under no obligation here. This is why we tend to say around here that R is a gift we freely offer for... well, pick your own reasons. Or not.
Why are you putting so much pressure upon yourself?
Because what is she actually trying so hard to become?
I think this is a great question to ask her. She might not have a great answer right now. I wouldn't expect an epiphany. However, I think the discussion might help.
That’s not some heroic transformation.
Heroic? Maybe not. Personally, I think the work I watched my ex do was impressive. I think the work I've seen a few WS do here on SI was impressive.
Similarly, I've been impressed by BSs who have done the work to heal themselves and address their own personal issues.
Change occurs when the pain of same exceeds the pain of Change. And it's very hard to do. And it takes time. Lot's of time. Lots of hard, consistent work. And it's always a work-in-progress, a constant, determined effort to be the best version of ourselves.
If you're up for it, read Marcus Aurelius' "Meditations." The Emperor of Rome spent many of his nights reflecting the day's events, his decisions, lessons learned, and how he might improve himself tomorrow.
Her best self is just the woman I deserved from the very beginning.
There's a line at the end of Clint Eastwood's movie "Unforgiven" (written by David Webb Peoples) that I've never forgetton. William Muny is standing over Little Bill, Henry rifle in hand. Little Bill says: "I don't deserve this, to die like this. I was building a house." Muny glares at him and says: "Deserves got nothing to do with it."
I find that tidbit of "wisdom" to be applicable in a great many situations in life. Deserves got nothing to do with it.
Do you think your wife deserves the GIFT of reconciliation?
So why did I have to be completely destroyed just for her to start becoming decent to me?
I know you're feeling destroyed, dear sir. I know. BTDT. I also know that one day you'll realize that you have not been destroyed, that you will heal, that you'll put yourself back together and come out the other side stronger and wiser. It just takes time and you're still in the early stages.
Be gentle with yourself.
How do I find peace?
You step back and detach from your WW, watch and observe what she does with the opportunity you've given to her. You focus on you, your recovery and healing. You lead your best life, on your terms.
I cannot pretend it doesn't hurt like hell to realize that the version of her I am being asked to believe in now, is just the version I thought I already had.
Yep! It's a mind-fuck of epic proportions. You don't have to believe it, Gemmy. Not yet, anyway. One day, years from now, you might feel comfortable with her and know that she's become an authentic human being. Or not.
How long you're willing to give R a chance is completely up to you. It's not a vow. It's not an iron clad contract or divine commandment. Maybe you'll wake up tomorrow and decide "fuck this shit, I'm done!"
The uncertainty sucks, doesn't it?
