Money Diary: A Trainee Accountant On 28.6k Who’s Just Moved In With Her Girlfriend

Welcome to Money Diaries, where we're tackling what might be the last taboo facing modern working women: money. We're asking a cross-section of women how they spend their hard-earned money during a seven-day period – and we're tracking every last penny.
This week: "I’m a 22-year-old trainee accountant living in east London with my girlfriend, L. We moved in together a few weeks ago so have had quite an expensive time furnishing the place, although a well-timed birthday has helped with some of the costs. L and I have a joint account we use for rent, utilities and groceries, as well as any other shared purchases like takeaway. Where any purchases are from the joint account I’ve just given my half of the cost. This week L and I tested positive for COVID-19, which means we’re self-isolating. I can work from home but L is a carer so essentially has time off."
