Mutual transparency would involve the sharing of daily schedules, open e-mail accounts (each have each other's passwords), financial info -- EVERYTHING. Marriages can't thrive on secrets, and each of you should be completely transparent with each other.
Boundaries are intensely personal, and only YOU know what they are. These are the "dealbreakers" -- the things you simply cannot abide lest they violate your own personal integrity. They are about YOU, not about HER (that would be "controlling").
