Glyn:

It may not be that much more common for the female to be the spurned on than the male, but it is definitely more commonplace for the former to be spurned by way of infidelity. When an abundance of suspicious activity is taking place, as is obviously the scenario of this piece, then it's only a matter of time before one is found out about. Then it can be a potentially dangerous period if caution is not applied. Sad to say so many people get killed over love triangles, and many songs have been written about this, going back to the folk classic "Frankie and Johnny." In yours at least both partied exit with their lives intact if not their egos.
