If you really, actually don’t give a shit, you can bounce. Work out a way to split assets with your partner and go do whatever you want with your life. Your family will probably hate you for leaving, your blood relatives and/or friends might lose respect for you, getting another job might be hard, but you’d be free and none of that would matter.
Unless you actually do give a shit, but just need something to change? Are you sure that giving up what you’ve got would be the change you need? What is it you want?
