Congratulations on getting your Hello from Heaven message from your husband! You recognized the communication from him, and that's what his goal was.
I don't think you chased him off by crying and telling him how much you missed him. He knows those things and knows you are especially missing him during the holidays.
I'll bet he gets stronger at sending his messages as time goes by. Just know that he is there for you, loving you as always. You did nothing wrong -- just showed him you are human, that you miss him, and that you still love him very much! :) Bet you'll be hearing some songs on the radio or hearing and seeing other Hellos during the holidays.
