It's all a mindset. I wasted many years of our marriage being irresponsible, selfish, and taking her for granted. But I've found that as I've made a concerted disciplined effort to be a servant to my wife, and to put her needs first, we've fallen more deeply in love than ever, and she has responded by wanting to be a better wife. Marriage isn't easy, but it's all about putting your spouse first and seeking contentment, then the happiness will come. :)
