The reason I am picking on it, is because I don’t really like that quote.
I don’t think Hashem is going to punish someone like that by saying, “Oh! I sent your guy, and you turned him down.”
Even if you made a silly decision, the punishment for silly decisions is not that you can’t get married.
(Also, I happen to think people should not be leaving so much to their parents. I think it is a way out of taking responsibility. Seriously, would you let your mother buy your clothes? Did you let her pick you seminary? Would you let her choose your job? It is good to ask advice, but I just don’t like the idea of completely abdicating responsibilty.)
