I respect your financial arrangement. I know a lot of couples who keep separate accounts for each other. Some of them have separate allowances to spend each month. I know some guys who have credit cards that they keep for their own personal use.
My wife and I have never done any of that. We elected from the start to keep all of out income in one account. All our cards have been joint accounts with the exception of a few that both of us are authorized users on.
I personally have always felt that the transparency that this provided was a safeguard against the loss of trust in one another. It was a way of show each other that we each were open book and had nothing to hide.
I am greatly disappointed that my wife would do something like this. It causes me to wonder whether or not she indeed can be trusted. She has repeatedly covered things up from me ever since I asked her to stop spending time alone with one of her male friends. Once I did that, she went underground.
It takes a long time to build trust, and just one act to destroy it. Not feeling too good about our prospects today.
