Roles change.  Love remains.  As you dance through life, those who come and go into your circle of love change.  That is how it is supposed to go.  Through change you learn and grow, but the one constant is that love.  If the love you are experiencing seems to change, then it is human love and not the everlasting constant of your true nature.  Come to know yourself and all that is as Divine Connection and the roles will not matter.  You are so very loved.  Never doubt this.
