After marriage we meet soulmate in our life,which should not divorce

How bad is your marriage? Are you in a country where ending it is feasible? If it isn't bad and there are few options for ending your marriage, reconsider your course of action.

Enjoy the "friendship" of this person,
The grass is not always greener on the other side.
How many times have I heard children say I wish your parents where mine(they tend only to see the best of them because they do not live with them),
It is the same with relationships. Be 100% sure there is no turning back when the initial excitement wears off.

If they are your "soulmate" you have all of eternity to come together.
"True soulmates" never come together through the pain of another.

I understand what you say, but hard to do.
