In two weeks I will have been married 16 years to a fantastic guy. But my first marriage was to a man who, after 15 years, two kids, me helping him get his master's, etc., became a complete shit overnight for no reason I ever could decipher. You will drive yourself crazy trying to understand such a man. I could write hundreds of are-you-effing-kidding-me pieces abuot him, but I won't.
