Relationship runs on wheels, with each wheel of three parts - TRUST, LOVE and FORGIVENESS. When one of these is absent, the wheel wouldn't go round and the relationship wouldn't move to the direction both individuals would want to go.
TRUST - It is the basic tenet of a relationship. You can never say you truly love someone unless you're confident to say you really trust him. Without trust, jealousy creeps in. Without trust, insecurity kicks in. Without trust, the relationship may fall apart.
LOVE - We sometimes misconstrue love with infatuation. Infatuation is defined as marked by foolish or unreasoning fondness. Love, on the other hand, is a profoundly tender, passionate affection for another person or a feeling of warm personal attachment or deep affection. My take on love is this: you can never say you truly love a person if you can point the specific reason why you love him. Love is never, "I love you because..."
FORGIVENESS – In the wheel, this is the harbinger of a relationship. If forgiveness is not present, it is an omen that the relationship would no longer work out. If trust has been breached yet you still love the person, forgiveness would be the forerunner as to where the relationship would go - either it would be salvaged or would end up in the garbage bin.
