I have two sons with my ex partner, we never lived together and he has never played an active role in the boys lives as of two years ago my sons have only seen him 6 times. I have no contact information for him, and no way of finding him I always give his family my phone numbers and address and ask them to pass it on but he has yet to call I would like nothing more than for my sons to have there father in there lives but I feel I'm the only one trying. My oldest son is now six and ask's a lot of questions and gets very upset when he see's his dad, as he is full of promises to come back the next day or week and never dose. He has never paid any money to myself for our sons and csa have never been able to find him. He doesn't send birthday cards or christmas cards or any kind of gift or letter to show his sons he's thinking of them or to explain to them why he's not around. Is there any way I can get him to take responsbility for his children and if not is there any way I can have his right over them taken away
