Thank you doggish - it's called being gentlemanly.
I would go out expecting to pay my own with my own money, but if it is not a group and just the two of you, it is the manly thing to do to treat the woman.
If it is the group thing, you go dutch...but the girl group rule the OP posted is correct.
I disagree. If it's a date, then I should pay because I'm asking you out in a different capacity. But if it's just a hang out type/platonic situation, you should bring your purse. I wouldn't pay for my male friend and I shouldn't pay for you.
