I listened to the magic touch shiur yesterday. Wow, does R’ Wallerstein pack a wallop. I loved the way he nailed the boyfriend by asking him to sign a document (which boyfriend refused to do), thus proving that pre marraige, there is no love. There is only taking advantage. Chuppah / kedushin is not just a ceremony. Its a commitment.
I always knew the importance of being shomer negieh (and how it applies to post-marraige as well), but the way he put it in perspective was a real eye-opener.
A must listen to shiur, no matter what your background / affiliation / gender.
The only lecture I heard that comes close was from Rabbi E. Buchwald, in his Crash Course in Judaism series (which by the way is also a really good series to listen to, no matter what your background / affiliation is)
