Why can't a schedule of the games be sent to him? Are practices not schedule? It should not be your "responsibility" to notify him of various ways for him to take part in his son's life.
Did someone contact you when he failed to pick up son from practice on his day? I really believe things like this should be documented. He can't afford to drop the ball like that!
You can't coddle him into being a good father. I'm not suggesting vindictiveness. You sound like a woman who has a good head on her shoulders, so stay sharp.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
