I've long said that I don't think most contractors track their expenses well. When they realize they are short and/or their suppliers/subs are demanding payment for long-finished jobs, they simply tell whoever they currently have a contract with that they need more money.

That said, things with this guy will probably never be good now. If you do allow him to finish the job, he will cut corners to try to improve his financial picture. Be careful, I've known contractors to sabotage whoever tries to finish the work or try to sneak back onto the jobsite and steal materials because they feel they have been wronged. (Even though the whole problem is most likely his own fault.) I've even heard stories about contractors damaging other property as revenge.
