He loved a girl he will never be able to get out of his head. They loved each other with ALL their hearts but there are no signs of reconciliation. He does not know this girl anymore. He just knows the memories still exist in his head and eat at him. He would not take her back ("You won't ask and I won't say") because I assume she left him and when she left, a part of him died. Death is irreversible.
