There’s always a dealer, darling. Only weed smells like weed; it’s unmistakable. If you can smell it, he’s using it. You’re not imagining this
If you confront him, he will almost certainly deny it. File the knowledge away and act accordingly.
If he’s promised to stop, or to save the money, he’s let you down. You don’t need him to admit it. There will be other signs. I’m sure you know and will be able to recognise them.
If you plan to get out, remember you don’t need his permission and you don’t have to prove anything. The choice is yours, darling.
Stay safe.
