apushatayid “If there is a “yes” from a girl, and he still drags his feet, he loses this chance and the shadchan will take the girl elsewhere.”
Which girl hasn’t heard the following:
“We heard such nice things about the family, but the boy is busy, so tell her not to wait, if he becomes available (and she makes it some where remotely near the top of his megila of names) we will get back to you.” This way he has no pressure despite that she gave a yes and he still hasn’t burned his bridge. Meanwhile she did exhausting research and invested emotion and now feels rejected. Supply and demand dictates that the ball is in his court.
I do agree that it may move her higher on his list knowing that she already said yes, but it certainly does not put him against the wall.
If this is going to change we need to do something radical. (and at the same time proceed with caution so it’s done right)
