Sarah
A girl I mentor is due in a week and her and her boyfriend broke up. He has all the baby stuff they bought together for the baby. He has no interest in being a father to his son. He told her to f*ck off and not to tell him when the baby was born. He will not give her the baby stuff and he has posted it for sale on facebook. Shes 17 what can she do? He technically paid for the items.
