My sister is an alcoholic, in denial for the most part. She does not want help or to help herself.
It’s so hard to watch those you love slowly and painfully kill themselves in front of you, So yes I get what you are saying OP.
I love my sister, I miss her and I would do anything for her but I cannot do anything to help her if she does not want to be helped, is your husband the same?
Waiting for someone to die as you watch on helpless, is horrendous.
For everyone who finds this mean or evil then IMO they are simply lucky enough to never have lived it.
I hope you can leave OP. You staying will not change the outcome.
