Invasion Of Privacy

When you are in a relationship is there such a thing as invasion of privacy? I have been keeping a journal for the better part of 27 years. When someone other than me reads it, especially without my knowledge, I consider that an invasion of privacy. Most of what I right comes from the deepest part of the inside of my heart and mind. My heart I seem to give away freely but my mind I guard with a ferocity that would rival the fiercest animals on the planet. My cell phone I am not as adamant about but I have a lot of female friends. Two of my best friends in the world are women. My friends and I have secrets that only we share. When those secrets are broken into like a thief breaks into a house, then my privacy has been invaded. I have a right to be angry. I believe there can be a certain amount of privacy within a relationship and that privacy should be respected. If you cannot trust the other partner in the relationship then you do not need to be in the relationship.
