You seem so hellbent on letting her know you know about the A...b/c you need that for your sanity...I know. But she knows that you know...she did it with the clues.
DO NOT TALK TO HER ABOUT IT......YOU SAY SHE IS VIOLENT IN ARGUMENTS....BRING IT UP....YOU'LL GET IT.....
The things you did before the M sound great you sounded very creative back then...do it again.
Go to a hardware or computer store and get those plastic coils to clean up and hide the computer wires. Put some silk flowers on your newly cleaned office.
Plan a surprise picnic, blind fold her and take her to the country.
(((((HUGS)))) For putting away the book......you are doing great!!!!!!!! Just keep moving, don't stop...don't think...just do it.
Trust me, you can change this sitch...I know you can... she will turn around.
