I spend on the women I date

I know there's a whole modern thing about going 50/50 and all that and I totally get it. But idk I guess I'm just used to taking the "provider" role if that makes sense. That's what I grew up seeing. Now I'm dating a woman who probably makes 2x what I do but I still cover all expenses for our dates, I really don't care. I only go on dates I can afford and so I pay for everything.

I guess what I'm concerned about the most is being taken for granted. I've never really known what to expect and some of my friends are of the opinion that I should make the women "earn" it. Not sure how to do that, and if they don't offer to pay but I still want to go out with them then I just pay myself. I really don't know what to expect/how to be treated in a relationship, I guess. What do you think I should look out for?
