Dear LFTP: the mother-in-law who sabotaged the cookbook

• What is the appropriate way to handle a mother-in-law who sabotages the marriage?

The reader reads a Dear LFTP letter: five years into marriage, the mother-in-law sabotaged a gift cookbook by altering ingredients so her son prefers her cooking, and took the grandson to Santa without asking. The hosts call her Cruella de Vil and advise an honest, boundaries-setting confrontation by the husband — moving away is cowardly. The 'Secular' answer is read and mocked: limit time, get recipes online, remember the kid won't remember Santa, don't cut her off.
