I've been offered my dream job abroad, but my partner's career is taking off here in India. This opportunity could skyrocket my career, but asking my partner to relocate feels selfish. How does one prioritise and balance 2 careers?

Whoever earns more by adjusting PPP, they should be prioritised more

Dreams are more important. Your partner doesn’t have to relocate till they feel the time is right. You do, even if it means short term distance.

Being a dependent, he is likely to find good opportunities once he rises in his career in India.

What's your dream offer?

My two cents - If you want to optimize on starting a family or just got started, it's a no brainer to stay together. If not, considering both's current situation and the career trajectory, you can decide based on which gives the highest ROI.

You can't balance both. Need to make a choice.

I would suggest moving abroad if you plan on staying abroad long term, better quality of life.
