i mostly agree with oomis on this one. i don’t wanna get screamed at, but come on! ur gonna live with this person for the rest of ur life (iy’h)! as much as you think you know the person by the time you get engaged, there is so much more to find out. an engagement period is time to get to know each other better, and come on there are just certain things you need to discuss like finding a place to live …………(i don’t feel like going thru a whole list)
so while i agree it must, without a doubt be in a tzniusdik fashion, you gotta talk to each other!
