There is a huge difference between a rule and a boundary. In the simplest words possible, a rule restricts the other person from doing something. A boundary doesn't restrict the actions of the other party. A boundary is a proverbial line in the sand of what someone will tolerate.
Rule: "You aren't allowed to fuck your other partners raw."
Boundary: "If you have unprotected sex with your partners then I would need to know their status before we have unprotected sex."
One tells someone what to do. The other gives the person the options and keeps everything clear and transparent. At the end of the day we have to decide what we will or will not take in a relationship and be able to talk about it without forcing a partner to do something they are incapable to do or simply don't want to do.
