Should I be Worried?

I’ve had a crush on a boy for a while now and for the longest time I only told my best friend, because I knew I could trust her. But the other day I decided to tell one of my friends that I’m not extremely close to about. Everything was fine until today in class one of her really close friends (that I know hates me) whispered something in his ear and he hasn’t really talked to me at all since. Should I be worried that she found out and told him? It’s not just about the embarrassment of him knowing, I’m worried that it will ruin our friendship he did find out.
