It is hard to say, not being privy to the entire session with your therapist; however maybe the therapist saw things in your behavior and comments that raised red flags in their mind.
When I relapsed at 6 months out of rehab, I was desperate to get back in. I called my counselor in a panic and his short to the point answer was "No" followed by "What would you learn this time that wasn't presented the first time?".
He told me what I needed to hear, not what I wanted to hear. Perhaps your therapist is coming from the same point of view. It is difficult to say with just a condensed one person account of the therapists comment.
I am just trying to see it from the other side with an open mind.
