You can truly experience deep love with your present relationship if you accept to experience deep love with all your past relationships.
Be aware that the way you are towards your past love relationships shows you how you will be towards your present relationships.
The maximum level of love you can express in your present relationship is not given by your capacity to place it above all else, minimising your feelings for others, showing indifference and detachment towards your past relationships, as a sign of love for your present relationship.
The maximum level of love you can express in your present relationship is the maximum level you can express in all your relationships.
