What do you mean by palm reading that my marriage is difficult?

There will be a marriage crisis, and my classmate's father is. He said he couldn't get through marriage when he was forty, and the result was true. Now his parents want a divorce because of his father's infidelity, and her mother refuses to forgive him anyway, so she says she has never been to the marriage hurdle. But you just said it was difficult to get married, and you didn't say anything unlucky, so don't worry, it may be a small matter.
