I had to go down to once a week for a while at the end of last year, and T told me it was an adjustment for him too...he said on Thursdays (the day I gave up for a while) he would look at his schedule and think "awwww..."
I saw him Mondays at 1 for a LONG time, and in the past few months have switched to Tuesdays. He told me he STILL looks at his Monday at 1 and freaks out when he has another client there instead of me
I know he doesn't feel abandoned at all, but it's nice to know when he misses me
