I think the DB'n is working, nice spin on the PMA considering the circumstances. He's really trying to work thru his issues, let him at his own rate. Your doing great. Make sure your not overly doing the PMA if he's in that state of mind. I know its a fine line, but that's why its one of the 37 rules.

I understand being worried about his suicidal thoughts, but it sounds like he's coming to you, which allows you to keep an eye on it. You know him prob better than anyone, and if it looks like its really about to cross the line, grab hold and call 911.
