id say its about the girl in the relationship being distant so the guy is telling her not to let go, and still be with him
but deep inside he really does want her to let go so they can move on with their lives and get out of this messy relationship.
hes "about to fold" it means hes about to give up on their relationship
so if she decides she doesn't want him anymore, he's telling her that she doesn't have to say anything or "waste her breath" on him, they can keep ignoring each other until she "fades away" from his life.
