"I'm really in the back seat on this, and feel not in control."
Then you need to get that control. Find some common ground with your kids. When your W butts in, tell her that you were in the middle of something with your son and continue on. You're they're dad and they're your sons. If I could find a way to relate to my two DAUGHTERS I'm sure you could do the same with your boys.
Go out and play catch with them. Take them hiking or camping. Go someplace that you know your W won't go. Take them fishing, hunting, or even just make a model or race remote control helicopters. Make it just YOUR time.
Is there any reason why you couldn't take your S7 with you to watch your older son play?

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
