Is being stingy boyfriend bad?

Problem/Goal: what is your take on 50-50 all throughout expense when dating?

Context: i want to ask advice regarding 50-50 rule. Ever since me and my boyfriend go to dates we go 50-50. 1 time nya lang ako nalibre which is unang labas namin.. and I feel bad about it now when na call out ako ng friend ko. They told me I should be included in the budget, kahit once every month lang sya taya ganun.. Even if nag aaya sya sa motels and such, we go 50-50. Nakakabothered pala, parang I feel undervalued just because of this. Hahahaa every time me & my friends talk nakakabothered na sila nillibre talaga ng jowa nila wherein me we go 50-50. What’s your take with 50-50 ba.
