I just read on a differet topic that the person who files has an advantage in the divorce. If you want to keep most assets and dont want her to use her gender for an advantage I would file. It seems that there have been a few guys posting that are going through a divorce where the wife wants to maintain he r old lifestyle but does not have the skillset to maintain a high paying job. (im generalizing and realize this is not always true) If I were you, I would atleast get a second bank account and have you check go there. Then put enough money to pay bills in the shared. It honestly makes no sense to share income if she wants out. If you go through courts they often make you pay child support and living maintaince anyways. I think she may hate you but realize you can still provide her with security.
