I think modern dating via apps made this very transparent: if you're usually paying for dates (or even if you're splitting) you will start to develop an intuition for some kind of cost per interaction and this can be quite important if you're dating in any kind of volume because the expenditure can add up. Eg I had someone tell me in NYC they're spending almost 1k a week on dating. That's obviously an extreme example but when your expenditure is that high it necessitates being analytical about how you're spending your time and money. Then if you already had that mindset, it's natural to see how it can extend into relationships (and friends and family). Ultimately, relationships are about give and take and we can only give as much as we can give etc. But there's always some implicit assumption of parity and even if you don't care for perfect parity, it's worth doing the audit once in a while to assess whether you're happy being a net giver or a net taker or if you need a reset because relationships of all natures can and have been broken over money.
