Someone's doubt/negative mind set/ misjudgements/wrong statement can break the bond/relationship of two person forever.
And that someone will never understand the pain through which the two close person go through or might it be the only one of them suffering and will just become a body without soul .
People willingly judge relationship , tear everything apart without giving a single thought that what harm could his/her statement can do . Better think before interfering , it might destroy those two persons forever !
