You can only lose that which you think you had (but which you never really did have).  You cannot lose love!  Love is given to you from the creator of all creation and it no sooner leaves you than it has some miraculous transformative effect somewhere else.  You have no sooner ‘suffered’ the illusion that it has left you before it swirls around from somewhere elsewhere otherwise unexpected, working its magic transformation on you.  So no!  Don’t despair a love long lost or short lost.  It is never lost.  It is given.  We are conduits as it swirls on through.  Every moment is a joy of love!  Every moment!  Always!
