I'll do my best to keep this short. I've known him 17 years, and he strung me along for 11 of those, thinking he was "ok." He will more often than not deliver nothing, and pretty much trashed my name in the process of ripping quite a few people off. He's a bit of a sociopath, but I never realized because I didn't buy anything from him. Seems that once he sees money in the equation, off goes his criminal side; otherwise he's Mr Cool. Now for me it's the occasional threat or intimidation by email(relax, he's all talk), but yes, finish up whatever you have going on and walk away. I'm still trying to distance myself from him in any dealings.
