Everyone says love hurts, but that isn’t true. Loneliness hurts. Rejection hurts. Losing someone hurts. Envy hurts. Everyone gets these things confused with love, but in reality love is the only thing in this world that covers up all pain and makes someone feel wonderful again. Love is the only thing in this world that does not hurt.
Love on it's own does not hurt. It is the negative aspects of people claiming to share or give love, who hurt you. When we do love and loose that love by death and not an intentional hurt by someone, it will hurt having lost that. Not because of having loved that person.
Most people don't understand love, they don't know how to love. Wanna be in love, think they are in love, wish to be in love, looking for love etc. Love doesn't cause hurt and pain. Stupidity does, with the excepting of loosing loved ones through the end of life.
