Yeah I do agree and endorse your views too. But when one proposes with a clear concept and good heart, at that time he is not aware of the role of destiny behind it. One should not rule out. No No... I am not defendin the persons who ditch or intentionally try to leave after proposing or say proposes with a mal intention. I am saying about the circumstances which sometimes force a person to even harder decisions even after shaping his life with previous hard decision, to destroy it. No sincere person proposes just for fun sake nor leaves for the fun sake too. And love is very much the other name of trust. So, one should trust his/her partner after knowing him/her pretty well that the separation was not intentional or for any ulterior motives but it can also be for the pressure of circumstances.
