Possible response:

"I will take over the house bill/utilities. $75 less of your paycheck will be deposited into the "joint billing account" so you can pay the credit cards from your personal account; therefore still having $325 per week if you continue to deposit $225"

Basically what I'm saying it that right now credit cards (in his name) are paid out of our "joint billing account" - I don't want to deal with those. I'm basically telling him that he can take care of the credit cards in his name and I wont be doing that from the "joint billing account".

Does that email sound okay?
