Chinese and Western culture in Marriage

Hi there,

I'm a British Black guy and I've been dating my Chinese girlfriend for over a year now.
She is a international student. She moved in with me with 2 months of knowing each other.
She wants to know if we have a future together.

We had an argument recently as we wanted to talk about marrying.
I wanted to discuss with her how we can plan financially and how we can help each with mortgages, bills and food. My Girlfriend said that in Chinese
culture that the man should pay for the house and that she will play no part in helping out at all.
She also mentioned that in China when the man gets paid all the money goes to the woman account and she will sort out the bills.

I'm a western guy and this came as a big shock to me what I was hearing. I thought a couple should share all responsibilities together.

I love my girlfriend and her parents are totally happy with us being together and I would like to see a future with her.

Can someone please give me some advice on Chinese culture and the roles a man and woman play in marriage.
How can we compromise?
