My favorite to know when to do something binary like this is to flip a coin with choice #1 equal to heads and choice #2 equal to tails.

When the coin is in the air, you will naturally hope for one side to come up. Choose that one.

That is a huge "cliché", not to mention that we are talking about things that may have a long term impact on your life and a rational choice must be done. Going impetuously like that is sub-optimal in nature. You may have bills to pay, and hope that the startup work/culture/founders will get better, while at the same time being miserable with all aspects of it.

Getting out of dodge doesn't mean immediately upend your life. But if you're unhappy with your work, your boss, etc. it might be a good idea to start looking for a new job.
