Tell an addict no and see what happens.
I still see him betraying his real interests and intentions linguistically.
He said “I have tried to demonstrate to you my commitment to sobriety.”
That isn’t “I am committed to my sobriety no matter what you do or don’t do.”
The first statement is about a show where your response—taking him back— is the purpose.
In the second statement, seeking recovery no matter what you do or don’t is the purpose. He isn’t saying that. His implicit threat of leaving the area, not staying in recovery all put the burden of his staying sober squarely on your shoulders.
That’s unfair and it simply won’t work.
His angry actions now confirm what he was really after and you said no.
You are making the right call for you most of all, but also this gives him the responsibility and opportunity to get out of his comfort zone and truly embrace recovery.
He may, or may not. Up to now it has been a demonstration, and his actions inconsistent and inauthentic. That’s my take. What’s your gut tell you about his motives based on his actions?
