50% owner of business that I financed and built. Want to shut the business down. Partner refuses. What are my options?

My idea, my money, my labor. Brought my brother into business. Very bad move. I offered him 100,000 to buy him out. He refused said he wanted the business and would buy me out. I stepped back in good faith. Now he changes his offer for past 7 months. I would rather shut the entire business down to save bad blood in family. He wants business for 40,000; it''s first 9 months of operation made 44,000 net profit. I know business is worth my offer to him at 100,000 or at the least worth 1/2 paid inventory and assets. He has a criminal record for being a thief I thought he changed. He has not and wants to steal business. I want to shut it down and split down middle and be done. What can I do? Thank you.
