I would like to update everyone:
I am very much aware that every situation is unique and requires daas torah:
B”H the person in question asked daas torah and with help of a Rav was able to show the parents how sincere and eager The boy and girl were about the shidduch! B”H they are engaged!!!
I can say that it was only after consulting daas torah that things set in motion because B”H the parents were eirlich enough to listen to daas torah and not make
excuses why it doesn’t apply to them or why s/o else has no right to tell them what to do ect ( which happens in some cases).
Thanks for all the advice and comments…with them I was able to help this friend organize thoughts and feelings in way that was presentable to parents!
