i don’t buy that most cheating is about novelty as such 🤔 i tend to assume it’s about gunk that builds up in the relationship that you don’t know how to clear. no gunk with a new person
TLP says it something like, a new person is someone you might be able to fool into seeing you how you want to be seen. the person you’ve been in a committed relarionship with for years knows too much about you to be fooled
... i think point is you should let go of your need for the image and accept that you will be seen to be naked and real and genuine and work from there.
