Dreaming of cousin

I had a dream that i had three very large diamonds and my phoppo’s son broke one and then gathered it and put it in a box for me, the very next day i had a dream that there was a flood coming and i was reciting Ayat-ul-Kursi, when my phoppo and the same son came to safety, his chest was covered in bruises and i was so relieved i hugged him.
Then after a week and a half i had a dream that his father, him and I are sitting together and he has a paper in his hand with another girl’s name written on it, i feel devastated and i get up and eat something sweet out of a box.

What do you think these dreams mean ? We were supposed to get married, but he found someone he liked and is secretly in a relationship with her.
