No, I'm sorry, I haven't changed my mind about the blog. Though technically still online, there's no way for the public to access it. It's hidden, and then some. Forever is an awfully wrong time, so I don't think I'll be able to guarantee that it will remain hidden for all time, but I don't see any chance of its current status changing soon. Even searching for it won't find it, not only is it hidden, but the door is locked.
In its absence, it has grown beyond the boundaries set up for it to be public and any change in that status would require changes to existing posts. No, I'm not talking about you behind your back, but there are things that really can't get out.
I suppose, if you're really worried about it, you could drop me a line and ask for a private permission, which is possible. I don't know if that would work, but perhaps your powers of persuasion are stronger than I thought.
