Sertapathy
A feeling of searching for who will betray you next after having been betrayed by someone. The feeling can be paranoid, curious, invigorating, or a mix, and is caused by a deep pain, mourning, and newly formed lack of trust.
After the wife betrayed her husband, he started looking through my phone. He is definitely experiencing sertapathy from having his whole world turned upside down by his wife and now he is looking for who is going to betrayed him next. It’s almost like he wants it and expects it.
