“The shidduch process in our community works something like this: shadchan suggests girl, boy’s side looks into her, Boys side agrees, girls side looks in and agrees, they date, get engaged and married.”
If we could reduce the time from original shadchan suggestion, to final yes for an agreement for couple to first meet, from say 6 months to 3 months, we may be on to something as it relates to girls marrying younger.
