I'm a little concerned that the majority of people here have voted "Agree" on #4. You think people should be forced to stay in a loveless/empty marriage?
If they have children, I think that they should at least make it work until those children are grown and out of the house. At that point, I don't see why they should have to continue staying together, although I wouldn't
force anything on anyone. This is just my personal feeling, though. I would never want to put any child of mine through a divorce if I could help it.
