I cannot tell you what to do, all I can do is share my experience with you.
My mother is the main alcoholic in my life. She has been drinking for 65 years, and, I don't mean socially. She has never been in recovery, and, never will be. She will die an alcoholic, there is no hope for her.
There were 2 times in my adult life that I went no contact, once for 4 years and another for 10 years, the most peaceful years of my adult life.
I set my bounderies and she now knows that I will enforce them, for my well-being, for my sanity. If she crosses them today, I am history.
Sending money is enabling, it will not solve anything, except make you broke, and, I am sure that is not your goal.
Going no contact, for me, was a win win situation it allowed me to regain my composure,
my peace, my life.
Do what is best for you, this is not a dress rehersal, this is your life, your one and only chance to live your life to its fullest...don't waste it.
