It’ll be interesting that a mother should put off a potential shidduch because a boy is 20 years old. Its likely that something else that was involved in this decision.
You write “one person pointed out, perhaps maybe the girl shouldn’t be in shidduchim if she just let’s her mother push her over,”
This mother has good intentions and isn’t “pushing her daughter over”. I’d be cautious dating this girl if she ignores her mothers opinion.
