call me frum…from what you wrote it sounds like Her parents called it off, not your Son…If her parents don’t want their daughter to be married with a full time learner, then why did it take 10 dates to figure this out?
Secondly, was there a connection between your son and the girl? If yes, then like others they can make it work without financial support from the in-laws…it is possible to work and learn at the same time…
