So what am I allowed to say? That this can’t be found anywhere in Shulchan Aruch or the Nosei Keilim? That, B’pashtus, not seeing each other when you want to for 7 days could create an issue of Dam Chimud? That there are several well-known stories of people meeting with their Kallah and R’ Moshe for a Brachah less than a week before their wedding? I’m not saying it’s a bad idea or not to do it. But we do need to realize that it’s not a Halachic necessity.
You can say all that.
