It may not be a bad idea. I did this about a month after I moved. I apologized for the way that I reacted to the whole situation as well as other things I thought I did wrong. I remember the counselor telling me that H was lost and had forgotten who he was, so she suggested that I remind him of who he is, so I also did that in my letter. I don't know if it played any part in him changing his mind...but I do know that it got him thinking.
