Hi Sophmum,
Thank you for posting. It must be very stressful holding the family together without support from your partner. I can that his drinking is affecting all of you.
I work for a charity called The Icarus Trust which is there to provide support for people dealing with the addiction of a family member. If you would like to talk to someone who would understand please get in touch. We have experienced trained people you could talk with and they will help you to know what other help is available in your area.
Maybe talking to one of them would help you to find a way forward.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
Good luck.
