Being in a relationship means that you both have to be ready to sacrifice for each other in both physical, emotional, sexual and financial purposes. There is no taking one and excluding the other, it's a full package that comes together.
Over the course of knowing what relationship is all about, I have come across certain arguments where it's asked whether a man must wait for the lady to ask for money before he provides it. My opinion on this is that once you are in relationship as a man, you mustn't wait for your woman to ask for money before you give her. You should know all your responsibilities and take care of them.
