Know that feeling well, and wallowed in guilt for a short while....til I woke to the truth that I need to take care of me, and if someone is sabotaging this, then I need to get out of their way.
You will get more from others here, and find that letting ourselves detach from this cruel game, has resulted in different endings. Some were dumped for more "caring" enablers, others were hassled to distraction and finally walked away, some saw their A hit bottom and "try" sobriety alone, whilst a few asked for help, worked a program and have changed their lives.
But it isn't about the A in your life really. It is actually about what you want your life to be, and how you want to live.
