for me marriage is sacred... as long as u can save & keep the marriage do it specially if u have children.

Now if u really did all ur best to keep the marriage but nothing seems to work & theres no LOVE at all... 

I guess the best way is to let each other go than let ur children sees all ur arguements everyday. As much as possible keep the friendship & open ur communications to him / her even only for the sake of ur children.

Who knows by giving each other enough time & space... Time will come & u will see each other again realizing in the end that "he/ she still the one for u".

"Even if  LOVE is full of thorns, embrace it. For in between those thorns there is a ROSE that's worth all the PAIN."
