Hi,
As someone who just watched my mother die of Cirrhosis, I think it's really healthy/important to detach. Unfortunately, if your AH didn't hit his bottom after having to miss his daughter's birthday due to being hospitalized, I would say that he is not capable of getting clean anytime soon. I'm saying this from experience. Detaching is the first step towards healing. I don't want to sound harsh, but for the sake of you & your daughter's healing: leave. I sustained psychological trauma from watching my mother's downfall, and I'm sure that you want the best life for your daughter. Sadly, I would have rather been taken away from my mother than to witness the hell that comes along with addiction. Please take care of yourself & your daughter
