>> If she breaks off the engagement she must give the ring back. If he does she gets to keep it.

But cynical folks could have called it “virginity insurance” for the lass who might get dumped by a faithless financé.
Happened to see on “Judge Judy” where the man broke off the engagement but the woman had to return the ring since there would be no marriage.
