My ex and I were not married but after 3 years we planned our baby together because of medical advice re me. Once I got pregnant he said he could not cope and needed time to think. He then got a new girlfriend and did not want to be on the birth certificate, though he did in the end. That is the only time he has visited his child. He never keeps in touch with us and does not send any money. I did not go to the CSA because I did not want to provoke him and the main thing I wanted was for him to have any kind of role as father. I even told him he could just come 3 times a year and see him, and he did not have to see me. No one in his family contacts us either, which hurts as I knew them well and often visited there. After 3 years, I had to get in touch for something else, and he did not even ask how his son was. This makes me really angry. Do you think that I should put in a CSA claim and invest it for the child's future? His father has plenty of money.
