@johnsonmarkus Regardless of OP and the owners not knowing what a CEO is, OP- I'm curious whose idea it was for you to put your money into the company, etc. What are your expectations, and what does your contract say?
The owners might not really think or care about this business that much, but it also doesn't sound like they have pressured you into any of this? I think this is just a lesson in boundaries and communication. In any business, be clear about who is putting in what (in terms of labor, investments, legal roles) and what they will get from it.
I'm really sorry you're going through so much stress right now.
