I am so sad because I'm afraid things won't work out with my girlfriend (Long post)

I am a man in my mid-30s currently dating a Chinese girlfriend who is six years younger than me.
Since I can speak Chinese, we communicate in Chinese, and I feel like we understand each other even better than when I dated Korean women.
Our personalities and conversational styles are so compatible that we text each other non-stop for about 8 hours a day.
The problem is, my mother is a master of Saju (traditional fortune-telling) who has studied it for over 20 years,
and she is incredibly accurate when reading the fortunes of people around her.
Sometimes, she can even reverse-engineer a person's eight characters of Saju based on the environment they grew up in.
My mother has always told me that my Saju is one where I can never be connected to my in-laws' side.
I didn't believe in Saju when I was younger, but seeing how accurately my mother reads them, I couldn't help but believe her.
However, my current Chinese girlfriend's father is extremely wealthy.
He owns a large house in the center of a Tier-1 city in China
and is an executive at a major Chinese construction company.
So, if I marry this girl, the structure of our lives will inevitably involve being connected to her family.
Since this contradicts what my mother has told me,
the thought that we might love each other and be so compatible, yet ultimately end up unable to be together,
makes me so sad while we are dating.
What should I do?
I am seeking advice from the older brothers here who have more life experience.
