After break up of an Eight ( years relationship, is it still right to say SHE IS MY FIRST AND TRUE LUV and vice versa for her?

Just curios, becos of when the going was good and all that was said, shared and done! Now its just an history, but deep down both of dems mind, can they ever share the same bond they once had with their new partners, dont 4get there are secrets involved that is discriminating and shameful!

Whats the house opinion on this?
