We can describe, flowing water as River or Waterfall.
River starts from a point ( mostly mountains & highlands) then it flows through many places but ultimately meets at sea or lake or another river.
So, here DV is river , 25 Ex - Gfs are places through which DV's life has travelled but Saachi is his ultimate destination.😛
In short, GFs may & GFs may go but Saruv goes on for ever.
Waterfall on the other hand also starts from a higher point & ultimately meets the plain land and for making its path to destination, it has to break many stones.
So, DV is waterfall who has gone through 25 break-offs to meet his love of life, Saachi.😉
Meaning of the riddle is, Saachi, tum hi ho, Ab tum hi ho,(DV ke) Zindagi ab tum hi ho.❤️
In all this life story, Anki is the jangli billi who always kept watch on her prey, 😲 I mean poor DV.
