Do you believe in fate?

How can I put it? There are some things you can't believe. My girlfriend and I are not on good terms. People say we can be apart, but I can't believe it. Fate is hard to break, but I still split up my girlfriend's parents. At that time, my father died and my mother was getting sick. People said she was in trouble, and I didn't tell the fortune teller. How did he know that his father was dead and his mother was dying, but it was quite accurate. What should you and your girlfriend do?
