Thoughts on being a parent

Today was the last day I drive my son to school. He is sixteen and decided to live with his mother, in the face of my new bride having a baby within weeks. With the chaos associated with a new baby and the rigors of life at one of the top high schools in the country, my beloved baby boy made the huge leap to face up to me and ask to shift to his mother's, after years of asking to live with me alone. My heart feels wounded, but I know its a step in his development that I can't fight - he is growing out of my shadow. I honestly feel like I have lost my best friend. For the first six years of his life, I had 100% custody of him, morning noon and night. My wife at the time helped about 10% of the time. After I filed for divorce, it went down to 60%. As of today, six years later, it goes down to 1%, by his choice. I am devastated. The impending birth of my second son is joyous in its on right, but there is a momentary hurt tinge due to knowing my firstborn has chosen not to be involved in the bonding time with his own little brother. As a child, all I craved was a father, and now my son has decided to live somewhere else, to finish his childhood. Deeply saddened and wounded. But I have a beautiful wife that I love and a baby that is due in days, so I will hide my broken soul and limit my random loss of emotional control to times when they are not around. I feel like such an utter failure as a parent. I guess its time to dust myself off and get ready to play Easter Bunny, Santa, Tooth Fairy and all of it, all over again. Once more, into the breach...
