I already know how the story ends, it was in the first and last frum novel I read.
He breaks up to go marry his dream girl. Girl #2 is so devastated and is stuck as a single. Little does she know that while running away from the break up that night she was the sole witness to a heinous crime being perpetrated on a certain car, that caused the death (murder) of an eishes chayyil who drove it the next day…. Many years later though, it all works out because she gets to marry the widower, who happens to be a judge, and who would never have gotten closure if not for this girl being so devastated and accidentally witnessing the crime…. and she lifts up the lechayyim glass to shamayim……
