Welcome to Just Answer. I am here to help you resolve your tax and finance concerns. Please feel free to ask anytime you need extra help.
Under the circumstances you should really consider using the married filing separate status. You will not be held responsible for anything that is your wife's yet you CAN claim all the things you paid for her care and all the other deductible items for which you paid.
This will place some distance between you and the POA .
Please feel free to let me know if I can provide additional assistance.
