Glass argues the same thing June.. I don't have the pp # handy, but Glass discusses PTS as well.
I can quote roughly here offhand that she compares the experience of infidelity fallout to be very similar to the behaviour of people who have been victims of a violent crime - assult, rape, etc
In short, they feel violated, vulnerable 24 x 7, and have nightmares that repeat the event or variations of it.. reliving it on a nightly basis
