"Keep in mind there is a reason you broke up – to put it simply, whatever the issues were, you couldn’t make it work."

Not necessarily. There may be good reasons to justify it. Or: There might be no good reasons..It might be that I just gave up, or didn't try hard enough, or became scared, or thought there might be better options, etc. That's why it is very possible to profoundly regret (or at least second-guess) a break-up, and the damage it can do, the hurt and heartbreak it can bring.
