Do you believe two people could be meant for each other even after years?

Like if a couple split up and went their seperate ways and the girl was convinced she no longer loved her bf, yet he still felt the gut feeling he did before they dated, that they were meant for each other? Or has anyone ever felt that? Like it was fate, and the breakup is only temporary? Has that feeling ever materialized for you? It's been over a year now since my ex split, but I cannot fight this feeling, I'm hoping I'm not crazy.
