Does he respond to your emails or write to you at any other times? If so, would reading these help with the connection? If he doesn't, could you maybe ask him to write you something brief once or twice per week (at the end of the session if he doesn't want to email)? Maybe he could record some sort of meditation for you that you could listen to when you need to feel the connection? These are the best things short of writing emails that have helped me to feel a connection. You could also do some visualization exercises. Not sure if you hug, but if so, you could imagine him hugging you. I know that it's hard and can leave you feeling too dependent, etc., but perhaps in your work you can investigate what part inside of you is craving this attention from him and why. There is the obvious answer (for me attention from my parents), but perhaps going past that to specifically why now, for example, could help. Good luck! and keep writing here if that helps.
