Because that's what people in a serious relationship do, support one another.
How is it a fair relationship to ask your partner to pay off half your mortgage and then to expect them to have no stake in the property?
This is a bit different to buying a new set of curtains or tv for the house.
In my situation, I paid half the bills and contributed to the additional cost in council tax. I did not contribute to the mortgage. You don’t think that’s fair?
