In this paper I provide comments on the Allen et al. paper (this issue). I note that it provides the first critical, comprehensive, and integrative review of extramarital involvement (EMI) to appear in the literature, and I summarize some of its major contributions to the field. I then focus on how the review stimulated my thinking about current and future best practices in marriage education for the prevention of EMI. I conclude by suggesting several directions for future research and practice. Key words: affair prevention, infidelity, couples.
