Hi my name is Sarah and i'm a young single mother. My daughter is only 7 months old and already her father has changed his mind back and forth as to whether he wants to have his daughter in his life. He has another girlfriend already and shes made threats to me. I'm wondering if it would be possible for me to go for primary custody of my daughter and maybe let him have SUPERVISED visits. He currently lives with his mother and the apartment is way under par for my standards as to where my baby would be staying and i would like to keep her out of that environment also. Also, if he refuses visitation rights under these circumstances, can I sue him for child support?
