I'm firmly set on not paying for a first date.
That's a little rude. Why won't you pay on a first date?
He should pay for everything since he can afford it.
That's very rude to do. Both parties should pay for the date 50-50. Not doing so shows your date that you are cheap and a possible moocher.
He should treat me since I'm the women.
Don't you think it's a little sexist to paint all females like that? A lot of women work hard to become equal to men, and they should definitely be proud to be able to front the bill. How about trying to split the bill once, and feel how nice it is to have some equality?
