You don't need to have a conversation about it. Actually you are probably on the hook for it just as much as she is right now since you're married. I'd make copies and see if it can part of the D agreement that she pays it.
For now, it's just her bill and you're giving it to her. If she starts asking you to pay for it or whatever, just say you'll talk about it later.
