I am having a problem collecting more CS from my son's father. Currently he pays me $500 a month for my 5yr old son and I have decided to put my son in a private school. The father and I have never been married we just had our son together. I currently live in SC and he is in California. He is currently military. We have no court order, this is just an agreement between us. Everytime he moves up in rank he increases the CS on his own. Everytime I ask him for more money he gives it to me without any problems. Since I have decided to put our son in a private school I feel that he should have to pay half tuition, uniforms, computer classes etc. $500 is not enough to raise a child on here in SC. It seems like since he has this new girlfriend he wont pay anymore money when I ask for it. They are not married and have no children. I am however currently married but that really has nothing to do with it. I asked him for more money and he says that he has a life and bills to pay there and refuses to pay me anymore. He doesnt call his son nor does he send him cards. His son loves him dearly and he knows his father but he fails to communicate with his son like he is supposed to. I refuse to let him take his son out of this state when he comes to visit because he doesnt call him. He does however send him gifts for his b day and christmas. I currently have custody of my son, we have not went to court for custody or anything but I have had him since he was born. can someone help me out here and tell me what i can do to get more money from this ungrateful father
