If you feel curious how it would be, just go for it! And I think you and T can talk in advance exactly how little or much you want him to share about you in advance. It is your call.

Myself, I have had long breaks not seeing T (I'm talking about over a month) during holidays, but I never had the urge to see another T. I have lots of other people in my life and I might reach out a bit more to others, but as long as I am in therapy, it is between me and T. But I understand it could be helpful for someone else to have a backup.
