Reply To: Whom did the shevatim marry?

I read somewhere (probably in the CR) in the name of R’ Yaakov Kaminetzky, that Yaakov originally only planned to marry Rachel, but then Lavan tricked him into marrying Leah. Once that was done, he was stuck. It wouldn’t be nice to Rachel not to marry her after he had agreed to. Since his keeping the Torah was only a chumra (since the Torah was not yet given), he couldn’t use his chumra if it would cause pain to Rachel.
