Mrs. A.,

How about this:

1) "We are no longer together." Change subject here.

2) "Mr. A. decided to take his own path." Change subject here.

Fact. Short. The subject-changing is your information control, not your disclosure.

imo.

Peace,

Gardener

With fruit, with weeds even; but gather them
In the one garden you may call your own."
