I live in a house with my sons dad,the house is his, my daughter lives here with me too, we have no physical relasionship and have seperate bedrooms. I pay rent and my share of the bills, I pay less than half as I pay for everything for our son. I moved in here because I couldn't afford to keep my house. I dont do his shopping or washing and we share housework. He's never here, always working or at the gym or pub. Would we be classed as a couple in the eyes of the tax credit people?
