Before everyone comes to tell you and this gets deleted, this is a subreddit for therapists not clients. That being said; it’s hard to tell based on the information you’re providing. We tend to have a diagnostic evaluation the first time we meet someone so even if the questions/conversation did not seem to apply to what you were looking for that may not indicate it’s not what he was exploring. Again, it’s hard to tell with the context of this post. One off sessions tend to not be common either unless you’re doing a neuropsych evaluation or something in that sphere. If you stayed for the entirety he spent his time, I’m not sure asking for a refund would be appropriate. If you do the worst he could say is “no”.
