I had to leave a T who I was incredibly attached to because he was hurting me. One of the issues was between session contact. He invited me to email him if I wanted but then shamed me for emailing "too much".
As I once read on here, boundaries can be like an invisible electric fence - you've no idea where it is but it hurts like hell when you step on it.
My advice would be to try to push through the pain barrier and leave. It will be very, very painful, and that pain will probably last a while, but even as I was still missing T1 lots, I realised how much more progress I making with a new T and how much better I felt generally. Now I don't miss my first T and I have passed through the anger and disappointment in him that I needed to feel and express.
Your therapist is being very disrespectful to you. I think moving on would be a good way to show yourself respect, and to value your own feelings.
