If anyone thinks that 'Meant to be together', is an excuse to to the worst possible thing that one can do to somebody who has shared marriage vows with you... Then I say BULL.
It means that you have totally defiled and taken advantage of and screwed over the person who has been by your side.... all while KNOWING that possibly you were not meant to be together with them... and that somebody better happens thru the neighborhood.
They say, once a cheater, always a cheater.... Anybody who is so completely bankrupt emotionally, morally, physically.... If they can change their mind whom they were meant to be together with today... They can, and might, change their mind tomorrow.
If two people are not meant to be together, then by all means, dissolve the marriage. But, to me, there is NO excuse for cheating... EVER.
