Meaning of sincericidio by John Rene Plaut

SINCERICIDIO I will explain it with an example (mine ) : We got along badly with my wife and nothing happened in more than 6 months. She said ours was over. Then I looked to the side I met someone and the thing was going great I went to his office and told him I had someone else : SINCERICIDO . First he thought it was a joke. Then, when I reaffirmed, Troy burned. Stupid, you idiot! it was the softest thing I ever received. It was for you to think again! You have to fire her right away!!! I went to an Inquisition court and promised to finish and she promised to forgive and forget! If a man can't win an argument against a woman, imagine what was against two (my sister-in-law). Well, I complied and I've been good. She half forgave, but only after 5 years, but forgot? Never!
