Hi,
Maybe your wife would be find it easier to talk with someone she doesn’t know about how she is feeling. If so she could contact us at The Icarus Trust. We are a charity that provides support for families and friends of those with addictive behaviours. She could talk with one of our experienced trained people in confidence. They would understand what she has been through which she might find helpful.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope that things work out for you and your wife. Good luck.
