When people CALL IT QUITS, they decide to break off their relationship, to get divorced.

Поставить точку в отношениях - значит завершить их.

However, it CAN also be used in cases where someone’s business is doing badly, so they decide to give up and “call it quits.” But for the most part, it’s about breaking up.

Здесь они много чего расписали))
