Your boss is a dick, so he's making it clear they shouldn't need you. Get that shit out of your head that the sky will fall for these people if you leave. It won't.

It's hard to believe, I know, but they WILL find a replacement and life will go on.

If I'm wrong, your boss should've learned not to work you like a whore.

I can feel the OP's pain man. GTFO. Quit.

I don't think the OP's boss is necessarily a dick. The OP may be putting the pressure on himself (he is a co-founder).

But my point is, no company needs you to be give 100%. Ever. Even if you are the only person who can do your job.
