well, for first... she is so much stressed out that she has said so, I'm sure she didn't meant not to have kids but only saying this to show her feelings or may be as revenge for not getting the time from her husband.
And for the next so called quaint option, I bet if he involves elders from both families at just a starting stage of his relation, he is gonna ruin it. Also the elders/parents from both side will get worried that couple is having problems from start and you never know how they'll react. Plus, once the issue is open to 3rd persons the lady will burst out her feelings at some point for sure that can result in more destruction. It's too early to involve any 3rd person. Let the husband try which he has not done so far!
