Complicated yes, but if the parameters are set from the very start, how can one argue?
I wouldn’t argue about his lifestyle. I just thought it was oversimplified to compare people to food. His relationship with breakfast food is one-way. It is only about what he wants for breakfast. His relationship with women is two-way and much more complicated.
COMF is trying to be upfront. If he knows that he cannot or will not settle down with one woman, at least he has the decency to let that be known.
Rather that than the many men who do so without informing their partners.
Should he instead be untrue to himself?
Of course not. Not for a woman or any other reason.
