Child Custody advice, what would you do, how would you handle situation?

You need to save up the money for a lawyer. You need to go to court for legal visitation rights. If you already have a court order stating you have legal visitation rights you can go to pick up your kids and take the police along with you to enforce it. If you go that route you had better make sure you have them back on time as if you are late she will call the police too. Also quit smoking and behaving inappropriately around your children.
