Hey, I’m in a similar situation to yourself. Constant cycle but mine is 3 weeks cycle. The remorse kicks in days later and promises about that’s it kick the habit but then 3 weeks later it starts again.
I’ve tried a few things even making appointments but they weren’t kept.
I really feel for you. Is he lying about when he’s doing it and hiding it? Either way I think it’s a convo when he’s not high to say this is make or break. That’s the convo I’ll be having shortly. Good luck
