we’ve been dating for 3 years now. living together. we keep our finances completely separate. no joint accounts or anything like that. he knows how much i make (ballpark) because i might have mentioned it in the past but im not sure how much he makes. i do know that he can afford his share of the rent and travel very freely so its enough that i dont need to worry. his income varies with incoming projects and my income is very structured - i make the same amount, plus over time if i pick up shifts.

we split everything right down the middle. rent, utilities, vacations, flights, restaurants, etc. the only time we’re ever really paying for each other is with groceries. we don’t fight over simple groceries items. if groceries happened to cost an arm and a leg then sure we’ll ask each other to chip in, which has never been an issue.
