My wife had a sexual affair in 1993 with her first affair partner, a second affair in 2007 with a different person, and a third affair with the first affair partner again in 2024 after he contacted her 31 years later. He called her at our office and said, “You remember me.” He told her a story about losing his father and a friend. She felt sorry for him and was also curious as to what he was up to. The call was 20 minutes and he asked at the end if he could call again. Without hesitation, my wife gladly said “yes”. They spoke again and a sexting affair began… It was so incredibly easy for my wife to re-engage with him. No hesitation, no second guessing, all in within minutes. She says she ended the 1993 affair because of guilt, shame, wanting to do the right thing, and wanted to marry me. I would think she’d had ill feelings towards her first affair partner considering how things ended between them. I also expected her to have learned something over the years with marriage counselling and 2 affairs under her belt. She has learned nothing. How does this happen? Why does this happen?
