A Buddhist said that I was doomed to have no husband. Can you believe it?

Never mind whether what he said is true or not. Even if what he said is true, don't worry. Because fate can be changed! The Shurangama Sutra talks about Guanyin Bodhisattva who wants a wife and children. Of course, you are responsive when you ask your husband! But you have to understand the way to ask! Otherwise, you can't get what you want in this life, and you can get it in the afterlife. If you want it in this life, you must recite the name of Guanyin Bodhisattva sincerely. Learn from the bodhisattva's great compassion and help the poor. Please read "Four Disciplines of Fan Xian" by Baidu to see how Fan Xian got a son without a son in his life. Amitabha!
