Dave,

Are you entertaining the thought of ever working with this guy again?

To save the relationship, if there is one, it's professional to just bow out. However, the question is: Will he really know why you bowed out? Should Dave tell him in an honest from the heart discussion so this guy truly understands he needs to modify his behavior to work in this business? I struggle with this all the time. I always ask myself, Why am I the only one that always confronts these people and tries to correct their behavior.

Anyway, it all boils down to your relationship with this guy. If he is a lifelong friend and business acquaintenance and you value his friendship, you owe it to him to correct his behavior. If he's just a recent acquaintenance, then quit and move on.

One more thing, the longer you wait, the harder it gets. Do it now!!!!
