Joint banking account?

Whitlynn
Me and my SO have a joint banking account and I'm thinking about separating our accounts again. I feel like we just can't have any money that we can put back into savings and it's really stressing me out. And I know this probably sounds bitchy lol but every time we go out to eat or the movies with friends he ALWAYS offers to pay for everyone. It may not be much, but it really adds up. 😩 How should I go about bringing up this topic without starting an argument?
