I was engaged many years ago to "Guy X"- a fellow who one day announced in his rather pushy way: "Ya know, when we get married, that means I get to read all your old journals!"
I asked him where on earth he had gotten that idea. His reply was a long diatribe about how married people shouldn't have any secrets, it was his RIGHT as my husband because the Bible says the man is the boss, and why was I so defensive, what was I trying to hide, and so on. When I replied that I truly had nothing to hide and he knew all my so-called secrets, but it was just the principle of the thing, mainly respect, he went ballistic, angrily accusing me of having sins and secrets and all kinds of horrible stuff. I finally got angry too and told him that I would burn my journals or rip them into wee pieces and clog up the sewer system with them before he would ever read them or even see them.
I'm actually grateful that he said that, as it was the beginning of my gradual return to sanity.... like my eyes were finally opened. Funny but there were a lot of other bad experiences there that didn't faze me, but this did. It helped me to realize that I neither wanted or needed a BOSS; I wanted a husband to be my lover, partner, and friend! It's a long story but I left him not too long after that.
And well, I've been married for 22 years now to my best friend, a man who loves the fact that I write and would never read my journals. I have nothing to hide, and he COULD read them, but I am glad that he chooses not to. He respects me and my need for privacy for myself, not because I have any secrets. That is what Guy X simply didn't get!
I hope the woman he eventually married was not a writer.
