From my point of view, it's always better to not pay for everything for a woman. A man degrades himself down to a lower level than the woman by doing that. For a healthy relationship both partners should be on par with each other and that means sometimes the man pays for the woman, sometimes the woman pays for the man and sometimes they pay for themselves. It always depends on the situation.

interesting ) I think, in Russia it is more often preferable for a man to pay for the both during a date (especially the 1st date) unless it is not agreed otherwise before. However, among friends of different sex, it is who has money that pays ) Though a man's generousity is always looked upon well.
