I always pay, even if the guy offers. My dad told me to only let my boyfriend/husband spend money on me.
but some women think that men are supposed to pay and some even think that men want to pay because that's what they were told, tell her to pay for her own food/drinks etc and she doesn't want to pay THEN toss her in the bushes but don't do it because she wants to get to know you before she has sex with you.
Ew.
For me, if I offer to take someone out, I'm obligated to pay, no questions. That's just plain ol' bummy lookin' and I can't do it
