They should be a model sort of marriage guidance couple. Look we been through a lot and we are still together and not just for death us do part its literally forever. Get over it already and stop thinking Divorce is the only solution. I am not really saying this right, I mean if you want a sort of "Model" or Guideline for marriage look to Esme and Carlisle lol they have been through so much. Couples considering divorce could learn from them.
I love the way SM kept that value going right through the books, this is love, perfect love and its forever its not up for a quickie divorce. It does not reflect our society at all and thats really sad, couples do not mean to love each other forever and yet here these vampires are and they really do envelop the concept of true undying reciprocal, unconditional love.
Don't get me wrong though sometime a divorce or seperation is the only forward, my Mum and Dad split up when I was four in truth they did the best thing. sigh.
