Of course it helps!

The syntax is a bit vague -I really am very rusty with Old(ish) French- but the last lines would probably be something like:

Show me a token (or, sign) of love,
And (if) you do not wish to (do so),
Then I must end my days
Pining away.

How much more is there? If you like, you could post the rest here, or, if it's long, send me the rest in a personal message and I could try to make at least decent sense of it: I'd want the editor's notes, though!
