My husband haven't talked or reach out to his kids?

Me and husband decided to separate because we are not the same page. He came over and wanted to have sex... I said NO.. He was upset and said if he can't get sex than no commitment. I don't want anything from him... he did enough. We have two kids together...2 and under. He haven't reached out to check up on them or asked if they need anything. This coming Wednesday will make two weeks. How can a parent not reach out to his kids. Is it to punish me?
