The bank doesn’t care where the payment comes from. If you can afford the mortgage payment, then go to the bank and make it. If not, and your name is not on the loan then it may be time for you to consider more affordable housing.
If you are legally separated then there should be some arrangement that spells out his financial responsibilities, including what happens to the house.
