Was Ayu's "A" single supposed to be her last?

[denadel]

This site has very good information about ayu's releases.
Some of the releases contains notes, and the notes on the "A" single says that this was supposed to be her last release.
Does anyone know anything more about this?
The notes of her "A BEST" album, which also was supposed to be her last release, says the same..

Also, didn't ayu write "TO BE" for matsuura? how are their relationship now? If he tried to end her career twice i guess it isn't any good..
