If his health would have been in grave danger, or if cheked himself into rehab pissed drunk then I completely understand, and you're right.

Rehab isn't something one goes and says, "ey I want to do it now, or maybe later!"

ButI hope you understand my way of thinkin and it's selfish thoughts that pop into ones head first. meh!!
BTW I'm glad he seems to be doing better.
