Whilst I do believe that fathers should support their children, I also believe that sometimes it is easier to just get on with it and do it yourself.
I had nothing for my children for ten years, for ten years I supported them myself because so far as I was concerned I chose to have them they were my responsibility. It was not until I could not work that the childrens father started supporting, he is really good now when he doesn;t have to be considering both my children are over 18.
Yet he is always phoning asking if I need money.
