I would definitely consult with a lawyer because we had to take a parenting through divorce class, required by law and it really opened his eyes to how his behavior in front of our son is detrimental to him. You need to protect yourself and your kids. You have RIGHTS, they have RIGHTS to see their father anytime they want to and at important events like the first day of school.
