Research has explored the perpetration of cyber dating abuse through an evolutionary lens, suggesting people use technology to perform mate retention tactics. Namely, previous research has found that mate value discrepancy and intrasexual competition predict the perpetration of cyber dating abuse. However, we do not yet know whether there is a direct relationship between cost-inflicting mate retention tactics and cyber dating abuse. Here, we directly explored whether cost-inflicting mate retention behaviours predict the perpetration of cyber dating abuse across two studies (study 1, n = 132; study 2, n = 124), finding strong support. We also explored the role of the Dark Triad in the perpetration of cyber dating abuse, and contrary to previous literature, we found no support. Our research furthers our understanding of the factors that drive cyber dating abuse from an evolutionary perspective
