Offer your partner to buy your half of the company and move on. The alternative is just to move on and keep the half of the company to yourself, which is something that he is not very likely to be comfortable with, so that's your bargaining chip. If you want to try and fix the situation, you will need a major shake, a shock therapy, something to make him stop and realize that things must really change. Simply making small changes (like getting rid of that designer friend) is pointless. If he does it, it will be to silence you and to go back to his comfort zone. You need a larger agenda, things will need to be different after dust settles or you and him will be back to bickering in no time.
