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
