This is really sad, I’m so sorry about your wife’s problems which are affecting you.
She obviously does need professional help.
It must be awful to hear the situations she is getting into, but it is not your fault.
Here is the Al Anon website, could you call them? They are experts and should be able to support you. Hopefully there is something similar where you are if you are not able to use the Uk helpline.
I guess all you can do is call the police is you hear through the camera that she is being abused. Read up online about alcohol abuse so that you understand it. Look after yourself too.https://www.al-anonuk.org.uk/
