Married with Kids or Separated with Kids?

Status: Married with kids.

There is a big difference with being married with kids and married without kids.
There is also a big difference with being separated with kids and separated without kids.

My dilema is : To be married with kids or separated with kids?

Kids are the sweetest and most lovable specially when they are young. When they get older, they learn to reason and have their own concerns with life. They get affected in different ways with the way their parents deal with each other. They make their own conclusions and analysis. Of course, you can't explain the entire situation to them. With the limited information they have they turn against you or are for you. Is it fair to tear the family apart?
