The easiest way to lower (or even to bury) partner’s interest is to make declaration of your love and fidelity. People generally guess it and postpone revelations as long as they can, but at some moment they give way and rush down the hill. Because they want to reveal, because it is a pleasure to reveal. It is like masturbation – once you’ve started you want to accomplish by any means. Then sufferings and reproaches will follow, but is there anything to reproach of? It is your fault that you couldn’t keep it quiet.
