i dun understand this

in the headline today of a chinese newspaper:

a lady stabbed her lover to death upon discovering that he is a married man.

and i think this isn't the first time this kind of news making the headlines.

what i dun understand is, why does one need to dwell with another person since both parties fairly well know that there isn't any love anymore? you are only cheating and being cheated.

it is another trade. trade of convenience.
it might be because of money.
or company.

not out of love.

and would u want to be still in this kind of relationship knowing that your conscience is shouting NO?

think about it.
you wouldn't want to be hurted that way too.
so, stop doing so to others.

what goes around, will come around.
do us all a favour, watch out for yourself.
