Destined with my ex

How can you say that you are destined with someone?

When you both feel the same way? When you love each other? When you face problems and conquered it all? When you already parted ways but still met each other at the of the road?

But who are you destined to be with?

With your bestfriend? To a stranger? To someone who really hates you? To someone you really hates the most? To your first love? First crush? To someone who causes all your pains and problems?
Or....

To your ex?

Can that be really possible?

To be destined with your ex.
