I am in a private company of which I am a 30% owner (according to the ownership contract and original investment capital). I lost interest in the business almost since it started, after an argument with my partner. The business is already two years old and not yet breaking even. My partner does not want to close the business down nor does he want to buy my part of the business back. He has since added more cash into the business without my approval and works without a salary. I do not want his time and money to be on my back. I have asked for my money back for the past year with many broken promises since. What should I do?
