Thr issue is some well a lot of females are gonna feel that u cheap, ur effort is too low, or that u not a real man. They may doubt that u really like them. Most expect men to pay most of the times.
My experience is different. Women know that a lot of other women use men for free meals and whatnot. So my theory is that if a woman offers to pay or insists that she at least pays half or makes it up for you next date, she’s trying to show you she’s not out to use you.
