Dont suggest to meet up. Just say "I thought I should let you know I will go ahead and have those lessons, our talk helped... Thanks for dinner"
Given the circumstances you did good. After that last interaction I was worried he would bring it up. I am glad he didnt. He actually seemed to me as if he was trying to make up for being harsh on you last time.
Dont push. He obviously cant be pushed right now. Easy does it sweetie!! xxx K
