I hear that. I was suggesting it in case you feel she is getting a mix of both yes and no, but obviously you know the details better than I do. If it makes you feel any better, my friend (tall and slim) who did all the right things and went to all the right places tells me she doesn’t find shadchanim helpful either. Slim, heavy I suspect they are just totally overwhelmed with panicked parents.
One suggestion I’ve heard from a shadchan (as well as a mother of marrieds), is to choose references with name recognition, though obviously that doesn’t always work.
Much hatzlacha in finding the right one simply!
