Hi Kimi,
I agree that it is important that you look out for yourself, while trying to support your husband. I hope that you have supportive family and friends around you. if you would like other support, The Icarus Trust is a charity which specifically helps the families and friends of those affected by a loved one’s addiction. If you contact us we could put you in touch with one of our Family Friends’. These are trained volunteers who you could talk with which may help you to find a way ahead and support you while you are coping with hard times. This is a free service so hope that you may give it a go.They could also signpost you to other services that could help your husband.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope that this will be helpful to you. Good luck.
