“When X happens, I leave.” What is your “X”?

I’ve seen a few comments about this and I’ve thought about it myself. Where do you draw the line?

I’m very rooted and I’m still trying to figure out what it would take for me to leave.

I worry I’m going to be the frog in boiling water. But if I were to leave I would be abandoning responsibilities I have to my family and it feels impossible to come to terms that. It makes me feel like planning to leave is a lost cause because I can’t do that to them.
