I think that our therapists are meant to "love" us in the sense that they want what is best for us. The Greeks had a word for a love which describes willing the good of another without any sexual or parental overtones - Agape. This is just a form of love for humanity in general. A person may will the good of another without even meeting them, for example we may will the good of people struggling with famine or war either with donations or simply saying a prayer. This was regarded as one of the highest forms of love and it is non exploitative and asks nothing for itself. So in a sense a therapist should have Agape for us. The concept fits in well with the Hippocratic oath that a physician is meant to do no harm and act for the well being of their patients.
