Not to brag or anything, but I lucked out in the mother-in-law department. She’s never once tried to undermine my relationship with my husband, and we’ve always gotten along freakishly well. Even the wedding planning was easy. She was fine with whatever kind of wedding we wanted, as long as I really, truly loved her son, which I did. (Still do!)
However, I’ve known enough daughters-in-law to be fully aware of the potential problems MILs can add to the equation. My own mother spent years trying to gain approval from my dad’s super-traditional mom, and while she eventually succeeded in winning her mother-in-law over with her Southern grace and charm, I know it took a lot out of her. She could have used a book like Sally Shields’ The Daughter-in-Law Rules: 101 Surefire Ways to Manage (and Make Friends with) Your Mother-in-Law. In it, Sally identifies the power struggles between MILs and DILs in a thoroughly entertaining way, and offers practical solutions for resolving these issues before they become a major problem.
