If I may ask, have you stopped using Facebook / changed how you use it now? Asked your wife to keep you logged out maybe?
I know what you mean with the irrelevant notifications. Lots of tweaking which notifications I get--still more than I'd like but it's an improvement. No games, no groups, no pages.
I've mostly stopped using Facebook. Besides that last check on Sunday, I haven't used it since. I still have an account, but I don't know the password. I could easily reset it myself, but its just enough friction to make it a pain. I also now have someone accountable to (my wife) and that helps a lot as well.
