The level of hysteria is a bit odd. As far as we know he's injured. And no-one has suggested he's striking or throwing his toys out. Absolutely nothing so far (as long as you ignore pricks like Duncan Castles).
Never go back. It's like when you've been with a bird. You take her back and convince yourself she won't s*** on you again. And then it happens, and you go into hiding to save yourself from the "told you so" comments. Or something.
