Her feelings of anger will bubble to the surface unexpectedly. Lead her in dealing with them by being calm, listening, but just like you did at soccer, not putting up with CB. Be the rock.

Keep doing what you've been doing to make your life better. Keep being a great father to your kids; that's obviously very attractive to her.
