I’m almost on the same page as Jewish and Working 22. The only role I see a shadchan having for a 25+ year old is to pass on the contact and then field the 1st phone call from either side if its to be called a pass. But if it goes to a 2nd date, the shadchan should back out, inless specificaly asked to intervene.
At 25, they shoud be able to fend for themselves. Problem is, today’s average 25 y/o boy has the people skills of a teen, so he’s cooked on his own
