That's the only way I know.

Push. Fight. Survive. Keep going. Rejoice with everything you have in the shining, albeit fleeting moments of victory (and no matter how long the actual time-span I guarantee, looking back they will feel like mere moments in the grand scheme of things.) Hold on to those moments and protect them like diamonds. For they are what will sustain you through the next round of pushing, fighting and surviving until you reach your next little, island sanctuary of victory.

The only thing consistent in life is change. For better, for worse, for indifference or for ugly. Things change. Nothing stays the same. Even the good times. Especially the good times. I'm not trying to be all "doom and gloom" here but fact of the matter is you cannot truly appreciate the good until you've experienced the bad. Only then are you capable of seeing the bigger picture.

Between the two of us, my husband and I had four divorces under our belts before either of us was even near age 30. Not something we're particularly proud of, but we both agree wholeheartedly as to the positive effects divorce has had on our relationship now. Our marriage has something that I don't think very many marriages have. A 100 % mutual respect for the loss that the end of a relationship brings. And not just for ourselves but for our children as well as our extended family and friends. Divorce brings about  loss to the entire community, not just those directly involved. It changes the world.
But so can a strong marriage.
