Unhappy? People are unhappy all the time. I'm sure the vast majority of people who've been married - with or without kids - has at one time or another (maybe even for extended periods of time) been unhappy enough to wonder about someone else or no one at all.
Kids are fun and all but they are on some level a sacrifice. You give up part of your soul for them. At the end of the day you should expect them to walk out the door not needing you at all and count yourself lucky if they say thank you.
There's no one (or there shouldn't be anyone) who can force people to stay together. That said, they should stay together. I mean, I think they should stay together if they don't have kids because they made a commitment and who wants to look in the mirror in the morning seeing someone who doesn't honor that but if you have children that should be double.
