If you both don’t already have resentment & trust issues, you WILL. Take bull by horns & wrestle the biz away anyway you can. Start new biz, take customers, etc. HUGE problem is nothing in writing. Even in writing there are problems but you get to refer to your agreement. Doesn’t mean you’ll follow it, but gives you a basis if u need court. I don’t know how people open biz with no papers? Is the biz even legal? I’ve learned over the years, but u still make mistakes. You should/will learn from this. I take it you r young? The positive is you r said to be successful. (I assume you have basic bookkeeping?). Best NOT to have partners. When you DO get papers together, TRY to put in writing any ‘exit procedures’. Buyouts, terms, etc. right now, this is basically a ‘rogue biz’. Eventually, there will be legal trouble. Tell your ‘bud’ you need papers drawn up to continue. Also, imo, he’s bullying you. Re: who works harder. Maybe both keep a work diary? GL.
