When the word “us” is introduced into any relationship, you know things are getting serious. What we don’t realise is that “us” isn’t really that big of a deal. It only becomes a big deal when you begin making shared purchases like a holiday, a pet, or when you move into together. Long term things, when your spending and plans become so intertwined it starts getting awkward to ask whether it’s your turn or theirs to pay for dinner. Soon, a joint bank account starts to sound like a great thing.
