The “best friend” analogy is really good. I never really got the whole “men always pay” thing, but that analogy really puts into perspective why it’s so unfair.
If you think about it, that’s a good way to look at everything in a relationship. If your best friend couldn’t pay for something and you easily could you might be happy to pay all the time. That person would probably not be your best friend anymore once you felt like you were expected to pay every time or they started taking your friendship for granted with how they treat you and your money.
