Should I confront or not?

Thanks, Starsky.
I talked to H last nigth about his absence and asked him to inform me his schedule in advance for the best of our kids. But he denied in a very defensive and rude way. He said he doesn't need to and if I don't want to take care of the kids, he can have full custody. But in the meantime he also said he wants to move out so he can focus on his work since he was ver busy lately. I know it is an excuse, and It sounds so unreasonable and inresponsible. How can he have enough time to take care of kids while he is busy at work and meeting the OW?
Anyway, H doesn't want to have the boundries. Though he claims he can take care of kids very well all by himself, but the reality is He even didn't have time to cook for them. He always let them eat fast food, and rarely checked their homework when I was not home. Most of the time I did the everything.
How should I deal with him?
