To Winnie: Why do you say its the minhag for the wife and/or her family to support a full time kollel yungerman?
Because it is, and although kollel is perhaps more common now than ever, it seems that it was like this historically for the few who did learn after marriage.
I would assume that he would first seek support from his own family first before asking his wife’s to support them and turn to his the machatonim only if his own parents are unable to help.
Why would you make that assumption?
