No, you cannot just pick up and move to another state. Were you married to him? If you were not, then you have sole parental responsibility, and he has no rights, unless a court determined what his rights are. If you move, you might violate the relocation statute if you go without a court order or his written permission. You have not given enough information here, so it would be best to have a full discussion with a family lawyer near you.
