My son has been addicted to alcohol and cocaine for 10 + years. Only in the last 2 years has he admitted it was a problem and wanted help. He’s had a few relapses but currently over 6 months clean.
Seeing what it does to a family, it is not a life I would choose for anyone. You’re not being harsh, he needs to kick this evil drug into touch for you to have a healthy, happy relationship.
It’s only my opinion Zoe, but I’d think very carefully before he puts that ring on your finger.
