Do you ever wonder why your self-control, rationality, and compassion seem to go out the window when dealing with your partner? Couples therapist Steven Stosny explains it all in this revelatory book about the divide between our Adult and Toddler brains. He shows the way toward overcoming these destructive impulses and nurturing the more loving and clear-eyed aspects of ourselves. Stosny draws on his decades of experience working with couples to distill his insights into an actionable guide for acting on our best, rather than our worst, impulses in our relationship.
