Cutetupid
Someone who ruminates on past events that they have no control, but it’s kind of cute watching them do it.
During reconciliation with her ex-husband Kim ruminated on the fact that the love of her life dated someone for about a year during the divorce - and actually had sex with this other woman. As Paul watched this folly, he recognized how cutetupid it was for his ex and future wife to spend any time at all thinking about his ex-girlfriend, who was inferior to her in every way. Paul pointed this out to Kim who wholeheartedly agreed and focused on their bright future together!
