I just want to say thank you for the original post as it is almost exactly what I am experiencing and it is a great comfort to know that its not just me.

And thank you to all those that replied. Your comments have given me more to think about and allowed me to accept that it is going to take me time. I am fully able to communicate with Sir but still felt that I was letting him down because I still struggle a lot and he has been nothing but supportive and full of patience. I now realize that I need to stop beating myself up about something that first isnt abnormal and second does not seem to bother him.
