Trust matters. After you’ve been hit, hurt, how do you feel about that person having care of your children? While a significant literature extolls the benefits of shared parenting, this paper explores what these limits are including through some reflections from single mother interview data. Conceptually examined through the often-competing lenses of hope and trust, these analyses frame the issues and considerations differently than through the more usual assessments of risk. Thus, explored are the mother’s feelings of broken trust but perhaps their continued hope and the resulting implications for supporting their ex-partner as a co-parent.
