What does I'm mean of a couple has broken up 4 to five times but keep getting back together

Depends on the reason why. If it's because of the same stuff over and over again, then theres something wrong with how they handle things.

Intense, might involve toxicity and lot of dependency or determinism and lot of growth.

Codependent and doomed to keep repeating the same mistakes.

Foolish. Why bother after the third time?

Work out and fix the issues or move on already

Or.... insane?
