Goodbye for now

Yes I know, goodbye for now,
How long? A year, a day?
Yes I love you, yes you're with me,
Here now, next to me, and worlds away!
See I free you, and I'll see you when I see you,
fine, OK?
Goodbye for now, again
Goodbye until whenever then
We're free, that's what we said we'd be,
At leave to come an' go, you as well as I,
Somehow each "hello" makes it worth "goodbye"
For now.
