I agree with smart cookie. Shidduchim are not disposable. People are literally desparate for shidduchim these days. If something suitable comes up, try to make it work!
I’m not sure that I agree with your point of view. I would think that a marriage is a lot less “disposable” than a shidduch — and so to suggest going ahead with a flawed shidduch may not be the best answer.
In truth, shidduchim are a lot like marriages (to belabor the obvious point). There are some defects that can (and perhaps should) be worked through, but then there are some defects that should completely shut the shidduch down (i.e. if one party physically hits the other, etc.). In the end, each one has to be decided on a case-by-case basis. There is no “one size fits all” advice for this sort of thing.
