From my own experience, my marriage went through a rough patch. Though for us, divorce is not something we believe is permissible in most cases. This forced us to work through our problems with the help of a therapist. With lots of hard work and time, we were eventually able to resolve all of our issues. Our marriage is now better than ever - we are happier, more intimate and better able to communicate than we ever were before.

Not having a exit hatch pushed us to persevere with our problems. I think if we had had less of a sense of comittment, then one or other of us would have bailed, and caused both of us and our kids a huge amount of suffering.
