svdad, you will get suggestions to cancel it. I would concur except the D isn't even filed yet. My suggestion would be to just watch and wait. If you start seeing her go overboard, then sit her down and have a conversation about spending and boundaries. My concern is that if you do something that upsets her she will file for D out of spite. I am not suggesting to appease her, but I am suggesting that you not rock the boat unnecessarily.
A lot of times LBS do things like cancelling credit cards in a passive-aggressive manner. That rarely helps your situation. Don't do anything out of anger or spite. I am a proponent of DBing. Detachment. 180s. GAL. Nothing in those principles suggest cutting her off financially. There are sitches where that is called for, I do not think yours is one.
