W still having affair with OP #2

[4mendmj]

Can we talk about the money talk? Actions, not words. I get it. Actions that will be done before talk happens. My direct deposit from work will be moved to my new account and I will have cancelled our joint credit card.

But I have to tell her...so as few as words as possible?

"I have changed the checking account my check goes to and cancelled our joint credit card. Here is your Amex card that is only in your name. Going forward I will be depositing into our joint checking account half of the sum of all bills for the home each month."

The end? She will ask me why... I am trying to think of the right answer and would probably say something like "When you spend our money on your infidelity, I feel taken advantage of. I have therefore taken these actions to protect myself and my money."

It is sort of like a boundary format but after the fact. Thoughts?
