I have been with my partner for nearly 9 years. 6 years ago I moved into his house but we moved and got a house together three years ago. I put no deposit down and he was able to pay half the house with the agreement I would have a 20% share. This did not happen and at times I have felt like a lodger. I pay the bills as well as housework and he pays the mortgage Iast night I asked for the commitment and to sort the original agreement is this fair?
