Just catching up with this thread now. Having grown up with an alcoholic father and my enabling mother, one of the best things I ever did was to move away and then eventually cut them off. Mother died last fall. I didn’t go to the funeral.
I have no patience with addicts. They made their own bed and they can deal with it. I am totally in favor of cutting your losses and walking away. If they wanted to get clean and improve their lift, they would. Instead, they drag every one around down with them.
