For love to exist in a relationship, loyalty must be there. For a relationship being healthy and long lasting, one partner will have to be loyal to another and that will strengthen their love for each other. But the feeling of loyalty is a thing that comes automatically to you and you can feel it towards him/her only whom you love from your heart. If there is no honesty in a relationship then there is no love. To make your partner feel that you love, you will have to show how honest you are.
