Why is he taking it out on the kids?

I just had a baby a month ago and we also have a toddler. We separated because he was talking to another woman the whole time. But I still want him to have a great relationship with his kids. The last time he seen them was 21 of Oct... the whole weekend. And I just want a break this weekend. He said no because of our issues and he still upset.
