Staying together just for the kids is a win-lose situation that will decrease your happiness and consequently the kids' as well.

Often in life you're not presented with win-lose situations. Instead, you're presented with lose-lose situations, and it's your job to choose the least worst solution for everyone involved.
To the post itself: It's a bit more complex than that. If the kids mean a lot to you then splitting up means seeing them less, making the "trade" times stressful for everyone, etc. It's a trade off like many things in life.
But I do agree that there are times that staying can be more damaging than leaving.
