I can only speak for myself. I am irrevocably committed to my wife and our marriage, and the preservation of our family. When I took our vows...I meant what I said. "For better OR for worse...". I wouldn't divorce my kids, even if they ignored me or mistreated me or caused me heartache...or whatever. And I feel the same way about my wife. That's just me.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
