Some outside of session communications:

So Monday my T called me unbidden to tell me he might be a few minutes late to our couples session. That call really helped me because I was on my way to the session and feeling extremely nervous (impending doom) and hearing T's voice on the phone calmed me, like hey, it's my T, he is gonna take care of this couples session and it will be all right.

Then today I had my individual session and had to email him afterwards about something I forgot to do in session. And he emailed me back within an hour.

These little things count for so much.
