Sacrifice or Valuing?

Love + Sacrifice = Marriage

People always calculating or predicting what is the value of a relations.
You love one more than the another party loving you or vice versa.
No one can weigh or balancing the value of love.

Yet, I believe everything is mutual. If there is no mutual committment by both parties, then this is not a workable relations.
One-sided love is always a form of stupidity unless you enjoy it.
It must be fair to each others. Neither one could only give, nor the other party does not take it.
This formula is wrong and thus the answer will never be revealed.
The party at fault would not realise the mistake until you tell him/her so.

Please be reasonable and rational when you are into a relations. This is the only formula to make things right !
