When does it become okay to quit something?
When your wife finds out:
I quit something when it becomes destructive in a way that I cannot fix. My last job stands as a perfect example. CEO was being investigated for doing something very illegal while simultaneously pissing the company's profits away on his own lawyers. I tried to fix it—I basically ran the company, I called in a few favors with PD and with some attorneys I know, etc.—but there reached a point where I wasn't capable of fixing that which was destructive in the job, so I helped my employees find other jobs and then I left myself.
