I am picturing you making exactly the face that Remus is in your icon!

Anyway, I can totally see where you're coming from with this. It must feel somewhat like you've had the rug pulled out from under your feet, because it's impossible to un-know the things we've read in the bio, and yet you've already worked to fill in some of those gaps yourself...

I think it's very sensible to make yourself new rules, and I'd do the same in your position. If I ever dust off my vast amounts of half-written fic (and I do feel tempted, every so often), it's something I'll have to work through too.
