not because it is a ch’shash of a bad get, but because it is wrong hashkafically to plan for divorce before you are married
Nothing against your “Rosh Yeshiva” (who could easily be anyone from YCT to JTS), but that is a huge Cop-out. Chazal were Mesaken so many things that went against their feeling of right (preparing an actual get for someone going to war, WHILE THEY WERE ACTUALLY MARRIED!!, and GIVING IT Al T’nai!!) in order to protect women from becoming Agunos. If his (if it is a “he”) shittah is that it is assur, say so. If it is that the women whose husbands are not giving them Gitten (for whatever reason) are not really Agunos because he wants to blame the victim, say so. What you quote him saying seems to be nothing but cowardice. Rav Henoch would have never gone for it.
End Rant.
