Do you believe that your marriage is divorce proof?

Even if things are okay, do you think that at some point you may not be able to hold it together? I am not necessarily referring to a third party stepping in. I am talking about irreconcilable differences that could at some stage bring it all to a grinding halt.

Are you certain that you both have what it takes to keep it going till the end? Can a person overlook certain things for the sake of keeping it together?
