Thank you for the response. It's quite an interesting situation as he acknowledges that he has some issues to deal with yet it's been over a year since he's acknowledged it and he still doesn't grasp that he needs the help and can't do it himself.
He has made some progress in attempting to contact a counselor/therapist/professional but then skips out without leaving a call back number or his name.
From what I can determine (although I'm not professional), it's not that there's one specific instance that 'changed' him....it was a result of a couple of years of disappointments and letdowns from friends and work. Also, due to his work, he was somewhat isolated so that added to his deterioration of his communication and social skills. One example is at our recently hosted Holiday Party and he picked up the butter knife and licked it clean and put it back.....he would never had done that before............I don't even think he thought about doing it...I think he just did it without thinking.
Anyway, I appreciated the feedback and response.
Take care and Happy New Year.
