We have a new paper in press at EJSP with Erica Slotter, Alexis Audigier, and Wendi Gardner about attachment avoidance and couple identity clarity. People who are high on attachment avoidance struggle to maintain a clear sense of who they and their partner are as a couple, in part because they are less close with their partners and because their partners do not accurately know them.
