There exists only one fact, one inescapable, irremediable, unalterable fact: "Mrs. SP" no longer exists. The person who used to inhabit that name -- gone. The woman that took her place can live or die and it doesn't make a damn bit of difference to me, because I don't know that person. She's a stranger who happens to have a relationship with my children. It's all back to the Latin root of "divorce:" divertere, to turn aside.
Mrs. SP turned aside. And now, to borrow a phrase, "I do" too.
You sound as stout as a brick outhouse Smiley! Good for you!
"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.
