I think it is good sign that he is checking on you....but, YOU do have to change the dynamic of your R, bc he won't.
I think its great that you have gotten to a point where you are not expecting a call (I am finally not checking the phone 10 x a day). I agree with mnt_dreams.......change it up.
For me, the key is to stop him from assuming that you are and will be always available to him.
I think you are doing great though! Have a wonderfully productive and happy day!
