Like someone else mentioned, this could be a good thing. At least you have leverage now in all future discussions with the boss because you've demonstrated to them that you are willing to take your talents elsewhere if the situation continues to stagnate. Your words now have much more clout. Be civil and completely candid with them. If they will not compromise, then stay the course and move on like your instinct tells you.
As for that company that leaked your resume, they have demonstrated a malicious and disrepectful attitude, so I wouldnt even consider getting a job with them.
