Thank you for sharing your story. Just so sorry to read of the nightmare situation you are in. I hope that your partner can take the help he can receive but wanted to tell you of some support that we could offer you if you are interested.
I work for a charity called Icarus Trust that supports people living with addiction in the family like yourself. If you contact us one of our trained and experienced Family Friends would talk with you and let you know what support you could be offered.
You can contact Icarus Trust on help@icarustrust.org or visit our website http://www.icarustrust.org
I hope this is helpful. Wishing you all the best.
