Our reading
An editorial interpretation.
The speaker presents the loss of friendship as almost unbearable, but keeps it within a hypothetical statement. That wording gives the relationship great declared importance without confirming whether either person considers it secure. The excerpt alone does not settle how sincerely the declaration is meant.
