Wow, it sounds like you have a wonderful t! Your description reminds me of my old t.
If I were you, in the next session I would blurt out..."with everything we're doing, what do you think about twice a week?"
Good luck. I know that's hard to do. I've been there. I think my biggest fear was that of rejection and I tried to remember that if he said no, he wasn't rejecting me but doing what "works".
Please keep us updated!
