Wondering Who Pays?
On the first date, it's better to go the old-fashioned way - the man pays. It signifies respect and chivalry. But after going on several dates and the lady doesn't at least offer to pay for the cheapest thing around, take caution as something might be "off" about her.
Our personality is in how we carry ourselves around other people. If there's something that doesn't align between you and your partner, that should be a red flag. If she doesn't volunteer to pay after several dates, spell trouble on future outings.
On the other hand, if your partner offers to pay or suggests a split in the bill, don't overthink about it. Gender norms are outdated nowadays. Most couples appreciate the idea of sharing responsibilities. Use that as an excuse to do what feels comfortable and what makes you happy. There is no valid fact on whether a man should pay and a lady shouldn't.
Never forget to check how they treat and respond to the waiter or janitor. A sensible spouse that respects and shows kindness to the little guy is more likely of good character. If they can't do such a simple thing, then the complicated ones will be an abject nightmare.
