It is not so complicated. Is your daughter mainstream BJJ. How relatively yeshivish is she?? This question will broaden or bridge the gap. And as for him , look more into him what is his hashkafa… where does he want to send to school darchei kav or drs kav ? Chaim Berlin ? MTA?? This will give you an indication where he’s holding! Which will also bridge or broaden the gap. A miut hamatzuy of guys in yu are yeshivish, probably picked up the hashkafa in Israel or wherever .. and are there for family reasons. Just like any other Bochur u got to practically see if it’s in the ballpark…
