Create a screensaver or wallpaper on all your computing devices listing all the shit your ex-wife put you through. In some detail, if it helps. Also how it made you feel. Never remove them. Even after 10-20 years. You need to be reminded not to get married a second time because memory fades and your DNA is always waiting to fuck with you. Your DNA doesn't care about you. Only itself. It will fuck you over for even half the chance to spread to another host.
