Love isn't something we give away and then we are empty, love is something we produce endlessly when we meet the right persons, i feel i am an inexhaustible source of Love, it goes with my real self and awakens to proper sharings and situations.
Nothing is forced and my being tells me when and to whom he wants to give that Love, which is simply the want of the other person, the need to share.
Sometimes the other isn't receptive to what we want to communicate and doesn't feel the same, that's why we have to believe that Love only belongs to ourself, so we are never stuck or dried up, another person, another situation will trigger our need of Loving, and only when we are fully satisfied, that we resound harmoniously with someone, so we will settle and can be faithfull to few, or one.
Freedom, communication, authenticity are key caracteristics to have gratifying relationships.
