If I remember correctly, your sitch is a little different than mine because of a confirmed OM.
However, I am glad to hear you still have some hope. Some thoughts for you that you can take or leave, as again you must make your own decisions.
These thoughts are: Don't confuse fighting FOR your wife with fighting WITH your wife Don't confuse being assertive FOR your wife with being assertive WITH your wife.
I got some of this advice from my professional C for myself. I also had the sitch where my wife had the higher income. I recently learned that there is some resentment for that I never knew existed.
So, again, you don't have to take my advice and it's no big deal. But I am choosing to fight FOR my wife and not fight WITH her.
