If there is a 50% chance of rain, does that mean we don't go out? Nope, it means you "prepare". That is how we should be treating marriage. You should go in knowing fully that this isn't a life long commitment because it is most likely to not be. Everyone should go in with a "best effort" commitment and it lasts as long as it lasts and as long as there is love. That would make marriage a lot less "scary" and far more practical and realistic. So don't get stuck indoors because of the weather forecast.
