My partner and I aren't married but we have 2 kids together and have been together 7 years.
We both own the house we live in, but I pay two thirds of the mortgage (& all our outgoings) due to earning more.
He owns another property from before we were together just himself (with a decent amount of equity) that he rents out.
Is it fair to split our outgoings this way? While I earn more right now month to month, he has a lot more in assets than me (his house and savings).
