I pay pretty much every time, except for once when the girl really was taking offense to my not allowing her to go dutch. I'm a gentleman so I pick up the tab, especially on a first date. But I pay very close attention to the girls who at least make the offer/effort to grab the tab or go half. It lets me know a lot about her character/personality. Generally, while I won't ever complain about paying I haven't asked a girl out for a second date if she doesn't even offer. I don't care how hot she is or how much money she comes from. I just don't like girls who are assuming or too old fashioned about things like that.
I am not in a relationship right now; but when I was, I was the one who paid, all the time. But that was because she was still a student and not earning, yet. If the relationship had lasted beyond her student days, I would've split the bill (though, as to how she'd have reacted to that is something purely hypothetical).
My guy and I mix it up. Last time we went out, I bought. Same thing if we are staying in, sometimes he cooks, sometimes I do. If by a lot of discussion you are referring in part to my earlier post, then you know I think it's more appropriate for the guy to buy the first date. Especially assuming the guy does the asking. for strong symbolic reasoning I've posted earlier.
Every first date I've been on, the guy has paid. I ALWAYS offer to pay for what I had or to split the check, but it seems like a lot of men want to cover the first date? At least that's been my experience. When your in an actual relationship, I've found that you both just kinda cover it on and off. I'll get the tab one night, he'll get it another night.
Years ago, I remember a guy who asked if he could take me out on a date. I accepted but I ended up paying my own way through everything. We saw a play together and had dinner. He never offered to pay at all. We didn't date very long.
My boyfriend has pays all the time ! I've paid for coffee a few times but I've had to do it sorta quickly.. otherwise he would pay! If I tell him I want to pay the response I get is nope this one is on me.. I treat my lady. Can get annoying because with that logic I want to treat my man.
