Do you and your t have contact between sessions?
Until recently I did not contact t between sessions. My in between contact has been limited to one specific issue.

Under what circumstances would you contact your t?
T actually asked me to contact her with updates about the situation. So I did. However she also said I could call her office number and leave messages/ask for more sessions if things were difficult.

What kind of boundaries should I set with my t?
I think that's a good conversation to have with your t. If you feel guilty about contacting her outside of sessions, tell her.
