Hi concerned_friend. Unfortunately, there is nothing you can do. Because you've always been there, he simply hasn't tried to contact anybody else. Once he realizes you have made the break - and mean it, he may search for some other emotional crutch. While he knows you feel sorry for him (quite natural) he'll use this to 'get to you'. Unfortunately, you're going to have to be incommunicado permanently. He is depressed, but you can't solve his problems if you want to get on with your own life. JessF is right, he is no longer your responsibility. He has to take responsibility for his own life. I would suggest, next time he rings/emails, be firm, suggest other options to him. I wouldn't email back, if he rings, as I said, be firm.
Hopefully Jess and I have given you some ideas how to handle this situation. Don't let him bring you down. He is a grown man.
