I agree fully that parental opinion should be valued – when the parent’s opinion does not carry a hidden agenda of the parent’s own vicarious wishes versus what the adult child wants and needs. Involvement is the not the same as interference. How many mothers of boys have refused a shidduch without even mentioning it to their sons, for the most STUPID of reasons (dress size was a 6, the girl’s mother didn’t have a choshuv profession outside the home, and the best one, the very intelligent one that someone said to me after grilling me for half an hour about a lovely girl – “but I hear she’s short, and I don’t want short grandchildren” — honestly if that’s a problem, why waste my time talking about her)?
And nowadays, it is not really so easy to walk away from a bad job, which is way better than having NO job. I would not normally feel that a bad marriage is better than no marriage, though. Nothing in our present world is ideal, and we have to remember that when our kids are in the parsha. Nobody said it would be easy…
