Welcome to the forum.
We all share the same common ground, we have a loved one who is addicted to alcohol or drugs.
Unfortunately I don’t have all the answers, but read the other threads and there’s advice and support on the home page.
My son admitted he had a problem when things got worse. He took part in a lot of AA meetings and CA meetings. He’ll meet others who are trying to stop, and if he’s serious about it, he’ll get a sponsor and they’ll go through the 12 steps…Google it.
There are some addicts in recovery on this forum.
Danman83 and BT1978 are really helpful giving advice too. Read their threads too.
I wish you and your partner well, but first and foremost he has to admit he needs help, and is willing to seek help .
Good luck Lx
