I find out of session contact to be helpful most of the time. There was a time where I was expecting sessions via text and we had to talk about it. And I didn't like not being able to have long texting sessions, but t1 handled it well and it's ok now.

Some ts deliberately offer out of session contact. It is very common with DBT. And some ts think that some clients need to practice asking for help and out of session contact is a good way to practice that.
