While I'm half kidding, I'm only half kidding. Every woman -- every woman -- appreciates a man who has a plan for the evening (subject to spontaneous change, of course) and who casually picks up the tab without making a mawkish show of it. This is basic and immutable.
That is half true, I agree with the last part, and I actually do pick up the bill for me and my gf (and gfs past) almost always. Because of where I live, most of my relationships are a little old fashioned - I choose and plan almost everything and she is expected to follow, and rarely does she want to go somewhere of her own choosing. That's just kind of how it is, not only with my current gf, but all of them past.
Specifically my current gf though, she has a bit of money of her own - so for the cheap stuff, I'll always pay - if there are several big ticket dinners or outings in a row, then she'll watch the tabs and pay for one or two as well. We split the rent and bills, and if there's a gift giving occasion, she gifts me generously. I don't shower her in gifts normally, we're just living a normal life together - however unlike some I guess, we would not break up over money-related things.
I also don't like discussing money at a dinner table or splitting bills, and that's not protocol in my culture either, so I have no problem getting up and paying the bill myself, and if someone else offers to pay the bill, then I don't fight them about it, it's because I've paid for plenty of tabs already.
