Mrs. Puppy did not have the universal vacant, dead-eyes appearance of an MLCer. Hence the distinction between a straightforward affair and MLC affair.
Is this the only requirement for her not to have been in a MLC? When I read the story it sounds like a MLC to me. The timing of the affair busting was perfect for breaking it up and putting her into depression withdrawal stage. Perfect boundaries. But she was still in a MLC to me. A roller coaster of events. Ups and downs, coming closer, distancing. Hormones out of wack. A perfect storm. Don't know about the childhood issues. Or the trigger event. But the actions seem just like a MLC.
The end result, also is something I question. After the affair is busted, what happens then? What is the end game? Is that like the end game in the six stages of MLC?
