I have always gone through this with T’s even the bad ones, even when I ended it.
Current T I am lucky. He gets a lot of transference from the Priest (Fr) at my college. Fr has allowed me to maintain contact even after I graduated (back in 2000) and when I came home for the holidays he always made time for a visit. Then he left the college for a Parish and I panicked... but he gave me a new email address he set up just for me and others like me that were “professional” relationships but not in his parish. We are still in contact. For a long time it was only one or two emails a year and he was always quick to send a loving reply. Since I have started with current T there have been a lot more emails to Fr and he continues to reply lovingly and promptly. I am hopeful that “terminating” with T will be similar, where I am allowed to check in here and there. I *think*, transference aside, he would be OK with this but I have not asked because then termination fears will take over our sessions. I also know that T doesn’t want to hurt or retraumatize with me so, with the exception of something beyond his control, he would not terminate in a way that left me wounded.
