Most Helpful Guy
This marriage won't survive without marriage counselling (I assume he's in recovery? Just because he's not using anymore doesn't mean he's in recovery - he needs to have some formal support too). If you're both serious about things, you'll go get some counselling.
It could still end in divorce if you can't work it out, but at least with counselling, you'll discover where you both are in the relationship, and if you both want it to work bad enough to make that happen or not.
