For the last year and half my husband and I have had a very up and down relationship with my step-son's mother. She has had 3 children with 3 different men. Each one she refuses to let them be a part of the child's life. The first 2 are fine with this, allow it and have stepped back. My husband on the other hand has been trying to be an active part of his son's life but mom would go months of refusing to let him see his son, stating that he needed to pay her and then he could see him. My husband was ordered to pay child support and has, he is current.
