Should I believe in astrology related to my marriage?

My family astrologer told me that I will get married twice in my life but he did not tell me what will happen to my first wife.

I am worried that she may die after our marriage. I recently fell in love eith one girl but I am very worried about her safety. I don’t want her to die because of that astrology prediction. Please help me. What should i do?

I will never forgive myself if she dies because of me.
