Bill, Hang in there with the falling out with your son. My middle daughter had one with my wife and I 8 years ago and did not know if it could ever be repaired..... well the great news is we are back together and it is so great she lives in Cranberry Twp and we are making up for lost time with her 9 year old son and 9 month old daughter. So hang in there and don't rule him out.
