So you’re saying that many people have trouble with shidduchim. It can be their family insisting that they marry someone not their type or their parents not being financially well off or their parents being sick or mentally unstable. ???
And then for other people, their parents are too easygoing or unconfident. Or something is “just wrong” with them.
So you are wondering why people with “normal” “regular” families, with a good background, pretty and smart, and always cheerful, would have a hard time with shidduchim:
Shadchand doesn’t come back with an answer
Parents don’t want to hear name
You aren’t sure yourself
Well, according to the title, your parents are apparently unrealistic. I’m not sure what this has to do with the situations you described, besides for them not wanting to hear the name.
What I will say is this: These are normal things that happen to people in shidduchim. It doesn’t matter where you come from and what your family is like. In fact, your family and circumstances have very little to do with the shidduch process. The One Above tells your parents to refuse to hear the name and the shadchan to not get back to you. He also put you in your situation, so He can get you out of if.
Just keep davening, and try not to ask “Why” too much – it may take years to get your answer.
