You know what makes a successful marriage in my opinion? Trust is one small part of it yes, however going into a marriage with the belief that it can't be just "thrown" away, or you can hit a "reset" button anytime something goes wrong is what makes a marriage last.

In some cultures such as the US, I believe we have grown into a society that allows ourselves to throw things away too easily, including marriage. Instead of fixing what might be broke, reuse, or make better we believe we can just toss the shit out the window and look for something new to replace it with.

If we are talking about marriage, the marriage should have only happened once the couple both have come to fully trust each other 100% and have committed to a life long adventure regardless of heartaches and shitfalls that might and ​will come their way. Sounds so simple doesn't it? Marriage should be simple if you truly think about it.
