It was in July 2007 when Mike L. asked the Pennsylvania courts to declare that he was no longer the father of his daughter. For four years, Mike had known that the girl he had rocked to sleep and danced with across the living-room floor was not, as they say, "his." The revelation from a DNA test was devastating and prompted him to leave his wife -- but he had not renounced their child. He continued to feel that in all the ways that mattered, she was still his daughter, and he faithfully paid her child support. It was only when he learned that his ex-wife was about to marry the man who she said actually was the girl's biological father that Mike flipped. Supporting another man's child suddenly became unbearable.
