In Australia, if you've been living with your partner for 2 years, you have the same legal status as if you were married (de facto marriage), but it sounds like in the UK you can live with someone for 20 years and it means nothing!
I feel bad because there are all these threads from mothers who are living in a partnership with kids and everyone is saying oh no you are financially vulnerable. Why should they be? Why shouldn't they get compensation for liss of income, for example, if the relationship ends or access to their partner's pension? Do people not see this as a feminist issue?
