Say goodbye, you know he'll leave. Say goodbye but don't say you love him. Say goodbye and kiss him before he leaves. Say goodbye and let go.
Say no, if he asks you to go with him. Say no, 'cause you know he doesn't want you anymore. Say it is his job, not yours. He is not yours anymore.
Say you'll forget him. Say you will, when he asks you to. Say it and don't let your true feelings show.
Then he goes, he goes away leaving you all alone in your big house and you grieve for him. Then he goes and you know you'll miss him until the day you die.
And if he comes back alive, you hope, you truly hope, that he'll come back to you. And if he comes back alive, you won't tell the thruth to him if he doesn't come back to you.
If he comes to you, you won't show your feelings, not before he shows how he feels. If he hates, you act like you don't like him, if he loves, you show your true feelings. But never you will be the quite opposite of his feelings.
Say goodbye, you know he'll leave. Say goodbye, 'cause you can't be sure if he ever again comes back.
