I have always paid the mortgage, council tax, energy bills. My husband has a good salary but has only ever paid the shopping. He left me and we are now separated, but his only contribution towards about £2000pm of these costs is £300 towards shopping (half the monthly shop). He is now renting. I begrudge paying his half of the mortgage now as we are separated. Should I expect him to pay 50/50 or should the financial arrangement be whatever it used to be? And is there any legal guidance saying so? Thanks
