You don't really say here what you said to him. But I got the impression from your earlier posts that you were kinda jealous of his other clients? So if he doesn't agree you have cause to be jealous because he keeps somebody for 5 minutes or whatever - it's not about what he is DOING and that he must stop it. It's about WHY do you feel jealous or whatever?

I get it. I used to feel jealous of my t's other clients too. Some of them hide in the bathroom when I exit, so I know I bother them too. I hated being able to hear him laugh with other clients. Then I was like, wtf, I used to do stand up comedy? Why am I not laughing with him? What's wrong with ME? why am I holding back? WHAT am I holding back?

I might have had too much coffee today...
