<human>: Provide a brief overview of the text.

My girlfriend and I have been together for 3 years. 
I am ready to buy a ring and be engaged after she's been hinting it for a while now. She is Fujianese and I am Cantonese.

In her Fujianese culture, the sons gets everything. That means her brothers will inherit the house, a rental house, (he already got a lexus car), and whatever antiques or money the family has while the daughter will get basically nothing.

Because of this she's been pressuring me on asking my parents for help to pay for wedding and/or a house. I told her my dad doesn't work and both my brothers still have to go through college so them having money to pay for our stuff is tough. 
To make matters worse, she told me in her culture my parents (Or me?)  are supposed to give a huge dowry to her parents (Like gold or large sums of cash worth 20-30K$) which we obviously cannot just shell out. 

I currently work and have only 8,000$ in savings making 50K/yr.
but even then I disagree with what she said. She even went on to say "Cantonese people are white-washed because you were colonized by Great Britian" so your mentality is different. Granted my parents are upper middle class (parents both were computer engineers/programmers)  while her family is lower middle class (her parents own a chinese take out) so I think the concept of money has a different meaning to her. I told her we live in 2015, not 1970 so her "tradition" to give dowry and inheritances doesn't apply.
Her family are very isolated from society. They have limited social interactions with other people since they work all the time and because of this their "views" are very outdated

I'm about to give her an ultimatum before I make a huge mistake in the future. Any insights/suggestions, advice on what I can do?
