Is there no way that you and/or your partner could switch to remote work? At least in the U.S., remote working is sweeping the industry. Failing that, could you get a remote job for a U.S. company?
If none of the above, is your relationship serious enough that your partner would be willing to sustain both of you on their salary alone? Could you quit your job, take some time off to recuperate, and then find a job you don't hate, even if it pays much less?
If none of those options work, and it just comes down to "my partner is unwilling to leave the city and I can't possibly be happy here", then it may just not be a workable relationship. Though before jumping to that conclusion, I'd have an honest heart-to-heart with them and tell them how you feel. It could be that you're more important to them than their career; you never know until you ask.
