What should my girlfriend's parents do if they are superstitious about fortune telling and say that we don't match?

Don't contradict his family head-on. Try to be nice to his parents. The most important thing is that your boyfriend is willing to believe this. If he doesn't want to believe this, it will be easy. He will tell his parents that I don't believe this. We are very good together. I hope you will believe me. Isn't it a little late to say it again? Anyway, whether it's your own fault or not, behave yourself recently and tell him that you don't want old people. He also hopes that we can be better in the future, but I don't. People who believe in this have been together for so many years. If it was really bad, we wouldn't be here today. Make more efforts with your parents. Maybe you've upset them. Pay more attention to yourself. If you love him, work hard.
