I agree. He has absolutely no right to read your journal, no matter what you did in the past. That was a SERIOUS violation of your privacy, and absolutely no one has the right to know what's going on inside your head. If we did, we'd be able to read minds.

I know how tough it is not to have a journal, I'd be lost without mine. It's just a thought but I've heard of people who set up special email accounts for themselves, so that they can email themselves their journal entries rather than keeping them in a book. Do you think maybe that might work for you? It's a little more secure if it's password protected, at any rate. Lots of hugs.
