That was a fun (in a bleak way ^_^) read. What I really enjoy is the fact that deep down it's about accepting who and what we are. Sort of like how in Sex At Dawn the author speaks at length about how humanity is programed for promiscuity (mixing partners no morality attached) from the way that we're designed to the way that we think and how infidelity remains a constant throughout the species.
They go on to posed the idea that infidelity shouldn't necessarily mean the end of a relationship, especially when assets and children are involved. Is the best thing to really end a marriage and break up a household for something as natural as wanting someone else and then connecting with them?
Similarly , with hypocrisy and economics, I think we feel a great deal of anxiety trying to hold ourselves to standards that are largely impossible to reach in all situations. The sad part is how much we'll hurt ourselves for falling short. Self compassion can go a long way for those falling off the hypocrisy wagon.
nailed it
