Writer's Block: Honesty is such a lonely word
Having been in a relationship for the past year and a half in which my partner and I have promised one another honesty, I would say that total honesty is both impossible and undesirable. There are things about oneself that one cannot and should not share with a partner -- to do that could not only apply strain on both people (oneself for feeling the need to always come clean, and one's partner for feeling the need to reciprocate), it would violate the sanctity of self that every person has and needs. Every person needs his secrets and private thoughts. Yes, you should always be as honest as possible with your partner and should not deliberately hide or lie about things, but you should not feel the need to tell your partner every tiny thing. That's just as abusive and harmful, in my opinion, as lying or cheating.
My fiancé and I made a promise at the beginning of our relationship that neither of us would hide our true selves from the other. We promised that we would not pretend to be people that we weren't or attempt to change ourselves so as to appeal to one another. With him, I can be as frank and open as I can never be with most others. However, because of this, I know firsthand how strenuous it is to keep up a pretense of complete honesty -- which, in itself, is dishonest. (It was after a fight brought on by such an attempt at constant honesty that we decided to ease up.) People can't be 100% truthful all of the time, even with the people they love most. There will always be secrets and little white lies, and that is the way that it should be.
