Love has no rules, even with black & white agreements couldn't compensate to the victim.

Someone can love you today, but stop loving you tomorrow. The scary part - we will never know when this [tomorrow] comes. There will be someone better, someday someone better will replace your position in his heart. You found 'your right one' but you may not be 'your right one' the right one.

Isn't that the saddest part of love?

All promises about loving you forever were gone. They become lies. Lies that everyone use it to console themselves.
