Dating someone who is richer than you are

I’m dating someone who is much better off than me. I want to split cost of all things we do such as concert tickets and meals out. I don’t really know why but I feel I should. He knows the difference in our financial situations and says he doesn’t mind and I believe him when he says this. He is a lovely respectful man who expects nothing back. I’ve recently said I want to split everything but this means that we can only do things that I can afford to do as well. So for example a meal out once every few months is all I can afford and if it’s something I can’t justify the cost of then we can’t go but we can do sitting else like a walk and coffee. He says he doesn’t want to do this and wants to be able to pay for things for me and doesn’t think he can be in a relationship where I won’t let him pay for things. At first I let him but after a while it feels I should not let him do this. I know this comes from the fact that my last relationship which ended 15 years ago was one with coercive control in and I’ve got used to looking after myself but I do also have a strong belief that women should pay their way. I know by budget and I want to be self sufficient. I do also have some fear that if he pays for everything he will start to lose respect for me and or think I’m a gold digger. I want him to know I’m not money driven which is true. I’m poor but I don’t mind poor. To can be happy and poor. Is anyone in a relationship where there is a big difference in finances and how do they manage this?
