Sorry for your loss. Don't blame yourself, it sounds like you were a good friend to him and that means more then what happened to him the last time you talked.
Sorry you have to deal with this Eve. Keep your head up and it is not your fault so don't place the blame on yourself.
I didnt know him personally but I know he went to SFA. A lot of people up there are pretty hurt as well. My prayers go out to all his family and friends.
