I thought I read somewhere you were D not separated. If I were you I would split out all accounts so all your finances are separate. Get your name off of anything your W pays especially if it can affect your credit. Make sure you have written communication between you and W about all finances i.e. email. If you are planning on taking the house over in the D you will need her to sign a quit claim deed and then you can call your lender and ask for an assumption. The assumption can typically cost up to 1k to file. The other route would be to refinance which may or may not be the best route. Weigh your options. As far as I know you dont need W to close the joint accounts, but communication with W would be best. Dot your i's and cross your t's.
How you split can be a function of your state laws. Mine are 50/50, unless parties agree otherwise.
