When i re-read my post about asking her to tell me about her plans; I really want to punch myself. Once again I'm letting her control my destiny.
AK I think we all want to punch ourselves when we think back on how we acted after bomb drop. When I think back it makes me so mad I want to punch myself in the dick. You should have stuck with the board to avoid most of those mistakes.
First and foremost you can't nice her back by paying for her braces or buying her chairs. Never has worked and never will work it will actually do the opposite and she will lose more respect from you.
Now you have young kids so if you want to stand that do so with zero expectations that she will return to the marriage. Your focus should be 100% on your children and yourself.
My guess is she is slowly planning her exit strategy probably waiting for the pandemic to end or until she latches onto another male.
Your best chance at reconciliation would be to tell her that this situation isn't working for you anymore separating and go start living a kick a$$ life. No one ever chooses this scenario so that is why there is so very few recons here. Most of the recons here are due to the fantasy blowing up.
She's very comfortable now calling the shots, having her own bed and playing house. That needs to change AK if you want things to improve. Things have to get worse before they get better.
