Even if it's 2022, why does a man still wants to help with the bill?

Two past dates and my current boyfriend have that same reaction.

Date 1: It was my invitation but he still wanted to cover more than half. He said it was nothing personal, just how he felt.
Date 2: He wanted to cover the transportation and didn't want me to invite me to an elegant place. Instead he wanted a cheap place.

My current boyfriend wants me to continue saving money and whenever it's my invitation, he prefers cheaper places and orders one of the cheapest dish on the menu. His reasoning is he doesn't want me to waste too much money. Whenever it's his invitations and it's a fancy place, he won't let me help. Even when it's 2022, why does a man still acts like a provider, still helps out with the bill even if the girl invited or orders a cheap dish on the list?
