To get over this sad affair, Stendhal wrote his famous book On Love, in which he described the effect of fear on desire. First, if you fear the loved one, you can never get too close or familiar with him or her. The beloved then retains an element of mystery, which only intensifies your love. Second, there is something bracing about fear. It makes you vibrate with sensation, heightens your awareness, is intensely erotic. According to Stendhal, the closer the loved one brings you to the edge of the precipice, to the feeling that they could abandon you, the dizzier and more lost you will become. Falling in love means literally falling—losing control, a mix of fear and excitement.
Apply this wisdom in reverse: never let your targets get too comfortable with you. They need to feel fear and anxiety. Show them some coldness, a flash of anger they did not expect. Be irrational if necessary. There is always the trump card: a breakup. Let them feel they have lost you forever, make them fear that they have lost the power to charm you. Let these feelings sit with them for a while, then pull them back from the precipice. The reconciliation will be intense.
