Tools & Skills Workshops board.Stripped to the basics, I describe this as a framework, "If you do or don't do ___ then I will respond by doing nor not doing ___." In other words consequences for the poor behavior.
Be aware of course that you will encounter strong resistance to impel you to retreat back to prior patterns. We call it extinction bursts. They're predictable but you may never know how long it might last before the other senses that you won't be intimidated or cowed into appeasing or giving up.
My now-ex and I had for years shared our accounts. But once we had a child the tensions rose. Every couple years we would have to replace a used car with another used car. This time - it turned out to be mere months before we separated and divorced - she refused to sign the J&S acknowledgement for the loan paperwork from my work's retirement account. The small dealer, a mutual friend, was livid.
I immediately went to an old friend and applied for a loan from his bank. The loan terms were that I deposit my paycheck into a personal account at his bank. (I'm still there, by the way.) Dealer was happy but now my spouse was absolutely furious. I had no choice but to stay firm, a new boundary for me. After all, it was her surprise objection that caused this. Actually, this turned out to be a good thing since within a few months our marriage had imploded and my paycheck was protected.
On a side note, better to not have any joint credit cards. You can be the account holder and the other be a card holder, that's okay, you're the responsible person in charge. But sometimes when there is a joint account and you suspend it, the other has equal rights to un-suspend it which makes closing the account very problematic.
