What is your definition of setting a boundary In a relationship?

Anonymous
Some idiot pink who shall not be named told me that telling my wife that I was uncomfortable with and not okay with a behavior my wife was doing was not setting a boundary, yet every definition of setting a boundary I have come across includes verbally expressing your needs and things you're both okay with and not okay with.

I don't mention this persons name because of member post guide lines, but the sheer idiocy of the comment cannot be understated.
