this is interesting too - and in common with what Shirley Glass says
"The very nature of being the "third party" (OW or OM) instead of the "spouse" means it's a fantasy relationship. When people are in affairs, they present a side of themselves that's not representative of the whole person. It's a special version of their best aspects, free from the normal responsibilities involved in sharing a total life situation; whereas the roles and structure of family life create many restrictions and responsibilities. A person's affair is not so much a rejection of the mate as a rejection of these role restrictions. This awareness can be especially helpful in dealing with our feelings of comparison with the third party."
