The fortune teller said that the woman's bone marrow was broken. Can we get married? Will we be happy when we get married? Please give me advice.

I am a man and find myself really fierce. I went to my girlfriend's house once in high school, and her grandmother hurt her foot the next day. I didn't know I had bone marrow at that time. Really fierce. I'm afraid to be with my family now for fear of killing them. My grandmother left early and my aunt left without getting married. I'm really scared now. The second girlfriend, her mother broke us up because of this. You decide for yourself.
