I think W has been following some sort of detach guide. Therefore, is it a good thing for DB that I will have the kids on my own for 2 weeks or will it just help W detach even more?
Yes it will. It will help you both detach and move on with your lives finally. You are obviously not a healthy couple. No healthy couple would steal money from each other.
Your are not trying to DB.. you are trying to get her out your life as she is stealing your money.
If your wife truly loved you she wouldnt treat you the way you describe.
A poster above asked if english your first language but you didn't answer.. is it english?
Just seems you tell us what a selfish person your wife is and then ask for advice like this.. im assuming because you are translating it wrong you dont understand what we are saying.
