Agreed @Onthedunes, @leopardandspots that was a great post.
I read somewhere else only a few days ago that this mechanism is also how an affair functions.
It went something like this:
The affair partner acts like a vanity mirror, their attention and flattery reflect back the betraying partner’s most attractive and desirable self, feeding a cycle of feeling good about themselves. Their betrayed partner reflects back their real self, because they know the ‘real’ them, rather than the sparkly new version of themselves they are portraying to the affair partner.
This feeds a cycle of comparisons between the affair partner and betrayed partner, where the affair partner appears to really ‘get’ them and appears to completely understand them, (i.e gives off exactly what they need to see about themselves, true or not, referred to aptly as “Ego Kibbles” on the Chumplady website ) whereas the betrayed partner, despite being completely in the dark about the affair, inadvertently becomes a source of guilt and annoyance (the one who actually ‘gets’ and understands the real them) and reminds them of who they actually are. They thus become an ego deflator and source of resentment and irritation.
The affair partner reflects a fantasy life with no responsibilities, a life centred on themselves on a pedestal. This life is only about them and the fulfilment of their desires.
The betrayed partner reflects back to them their responsibilities, their true ‘known’ self, warts and all, and reflects back their wrongdoing, guilt and shame.
Their affair partner thus makes them feel like King and their spouse cannot ever compare favourably during the affair. One gives off reflections to inflate the ego and the other gives off reflections of responsibilities neglected and love betrayed.
On discovery more often than not, a good dose of reality kicks everything into touch. It forces them off Fantasy Island.
If the betrayer is prepared to fully face reality and therefore the real them, then they might finally appreciate the one who loved them for who they really are and see the value of that kind of love.
Sadly the betrayal can be too much for the betrayed partner to take, or their partner’s epiphany can have come too late and the relationship is over.
Some ‘talk the talk’ of remorse and of personal growth, but can still never face who they really are. They continue to find anyone who might reflect that truth back at themselves an irritant, so even though they re-commit to their primary relationship, over time the relationship corrodes.
If a person can’t face themselves, if they won’t do anything to try to be a better person, if they don’t appreciate their good fortune to have someone who loves them for who they really are, then you are better off without them.
Until they do, they will never change their ego-inflating coping behaviours. In all likelihood they will probably repeat their destructive pattern with someone else.
