So Hashem decided that ALL Chasiddishe girls will get married,
while others wont??????????
Francorochel3 is correct that Hashem is the one running the show, and has indeed apparently decided that a higher percentage of chassidishe girls will get married than girls from litvishe homes.
She’s incorrect that we can sit back and do nothing and be someich al haneis, and she’s misunderstanding the Chazal about the bas kol, which was never meant as a guarantee that everyone will get married.
