Hi there, you said you had hoped H missed you while you were away, you never know he may of. I wouldn't focus on that though as you said his head is very busy at the moment. I would concentrate on you and on creating your own happiness doing whatever it is you like to do. GAL to the max and he will soon see that you are busy and happy in your own right and you never know he may just want to be a part of that once his work worries calm down.
I hope I haven't spoken out of turn here as I know I could be missing something from your sitch that I haven't read.
I wish you good luck in getting better though......
