Mature love is the ability to give love with no strings attached. Purely immature love, which Dr. Ankenman calls infantile, tries to take love through demands. In between immature and mature love lie the love defects of work-for-love and work substitute. People functioning under these defects believe they should be loved because they’re done something for another person. Love is not give and take, but give and receive in faith. Those able to sacrificially love only their own families Dr. Ankenman calls tribal. Others know how to give emotional love, but only in a shallow way, especially to strangers. Dr. Ankenman calls this diffuse love.
