Actually, Phoenix does make a valid point there....

IF it had been your wife posting on this board, that she felt like she was in danger
Because of your behavior while on meth,
I would have advised to get out of the situation immediately.

I hesitated at first to write this, as I have also witnessed first hand,
People threatening others at gun point, while in meth psychosis,
 And bashing others with baseball bats and such,
And those very people would not dream of doing such things in recovery....

However, that being said,
Phoenix IS writing the truth as well~
Brain Tumors can indeed cause people to act out in violence...
AND, I , myself NEVER became violent , no matter how spun I found myself.

Have you considered an inpatient treatment program?
