On Tinder dates, if more expensive than a quick coffee, i would always INSIST on paying half. Then there is no room for 'my turn next time' or worse, an expectation of some sort of sex . If it was just a coffee and they insisted 🤷🏻♀️ Meh i didn't argue.
My boyfriend, whom i met on Tinder though it turned out we had loads of mutual friends, (some across continents!) insisted on paying on our first proper date as it was really important to him to show that he matched what he perceived is my lifestyle and he wanted to be seen as a proper contender. This is just how some men work.
Tbh i was so desperate to get back to his and finally shag after a week of chatting and two casual coffees (at his, so no previous bills), i cared not a jot.
We now take turns about 5:1 as he is childless and comfortable and i have more life expenses (kids etc). But we are fully, fully together as a couple planning our future together. Also in around 5 years time, it is v likely that i will out earn him, so it'll be my turn to put more in the pot.
