Cap,
Are you sure this one is actually a WW issue instead of a Cap issue? I know there are plenty of members here who are very quick to jump on Mrs. Cap for even the slightest perception or wrongdoing (rightfully so since she was an iceblock for years), BUT you also know there are many members here quick to jump on Mrs. Cap.
Your last couple posts have given the vibe of being rooted in fear. The more progress your wife makes in her efforts, the more I see you seeking negative feedback about your W from a group likely to give you the confirmation bias type responses your lizard brain needs to keep her at arms length.
It would make sense. She abused you on an emotional level for years. You never thought she would put effort into getting better, and you resigned yourself to putting up with a "roomate/pseudo-wife" for the rest of your days. You got comfortable in your own numbness. You entered into this counseling with a preconceived notion that she was full of shit, and it would lead nowhere. You may have expressed a glimmer of hope, but you never truly expected anything to change.
Now you're starting to see changes, and you're seeking justifications to keep your wall up. If you let that wall down, then you give her the power to hurt you again. Are you really ready to let your wife back on your team again?
FWIW...I could be totally wrong, and that's okay too. It's just the vibe I get from your posting history, and I only hear your side of any story.
When your wife was actually being detached, cold, calculating, and was unwilling to admit she had work to do on herself...that was when you protected her the most. It came across as a sibling-like, protective form of love. You could vent about her, but the minute someone else said something negative, you were (at least on some level) right there to her defense. You made a lot of excuses for her when she was refusing to try, or at least gave plenty of reasons why you chose to stay. Now that she seems to be actually trying, your posts have shifted to a tone of subtly seeking others to confirm she is in fact irredeemable.
From my side over here looking in, it seems as if you are (if only a little) starting to punish her for trying, not because you want to hurt her, but out of your own fear of letting her in again. Self preservation. Can you bear to put yourself in a position where she could truly hurt you again?
She was awful to you for a LONG time. It really is okay for you to never trust her again. If that's the case though, you owe it to yourself to admit your own truth. Cap is worth putting himself first. Admitting your deepest fears to yourself is a huge step in the direction of taking away their power. Ultimately, you get to make the decision of which outcome you desire. You can't force it to be where you actually end up, but there is power in admitting what you truly want.
She could do everything right, have it come from the most authentic places, and it would still never make you a bad person for walking away. At the same time, you don't have to reject her attempts to grow in order to justify staying for reasons that don't include a desire to be vulnerable to her, and love her like you once did.
I get the feeling that, now, the ball is finally really in your court. When you've been battered like you have, that's a scary realization to admit. There is no right or wrong answer, but there is what's right for Cap. Only you can decide what that will be.
