Honestly now. Guys normally pay for the first few dates. Sure.
But when you've hit the stage of couple you're expected to pay for yourself. Anything else is you either having no money, he having too much or you being a gold digger. I know I know, blunt. But that's the way of it. Obviously taking turns to pay for everythin might be easier.
If you guys are fine with that arrangement then I don't see a problem with it. However, I would think a guy was stingy as hell for that. I don't mind paying for both of our meals every now and then. Food is a need and it's important to enjoy food so it's not a big deal to me. But if he's so resistant towards paying for my meal ever, then I will honestly think he's stingy and cheap or trying to make a point when it comes to gender roles to an extent where it makes the relationship feel different. It's nice knowing that your SO will treat you to a meal every now and then.
It's perfectly okay if you feel that way- if it makes you upset then tel him, if it does him find out how to resolve the issue. Initially no one should really have a problem splitting really- in the rules of being fair.
