Jax: Tizkeh L’mitzvos. very well done!
PM: As a rov of a community then certainly you are well aware of the difficulty the girls in your community are having with shidduchim.
I would be very curious for you to do a study (although it would be quite a limited sampling) on the couples that come to you with shalom bayis issues and see if 22.5 21 have more difficulties than 23-19.
I have discussed the shidduch situation with each and every one of them (that was my only reason for speaking to them as I have zero interest in wasting their time). They have all peh echad srongly backed encouraging more close in age shidduchim.
You touch on the silver bullet in the shidduch crises.
If come Tu B’shvat/Tamuz boys are only permitted to date girls 21 and older, and to date younger girls a boy must wait till after the zeman, then boys will have a strong incentive to date girls their own age.
They have been approached numerous times. To date they are reluctant to make such a rule even though they are well aware of how serious the age gap problem is.
Why they are reluctant? That’s not for public debate, although I strongly encourage every cr member to bring it up with the powers that be.
