Man Always Paying On Dates?

Do you ladies believe that the man should always pay for the date? 
I believe they should only if they offered and refuse to let you pay. 
My bf pays majority of the time because he always wants to but i always help with the tip and i will pay as well, he doesnt like me paying for it if the bill was expensive. I find it ok for the lady to pay, its a treat for him to not pay for once.
