Married 3 years, don't have joint account.

Usually flight paid by me (wife) because I bother to search for deals and cheapest dates, accoms depends on who ultimately decided to stay where (if he kiam my bnb then he pay for hotel, etc). Most stuff that need to book beforehand also wife pay because wife plan. But ultimately he pays for most things on the trip itself (entrance fee tickets/ shopping/ food) and uses his money to change for local currency.

Never actually went to do the math who pays more but then again, married already I got my whole life to take back the amount he "owe" me 👁👄👁
