My sons father hasn't been in his life and my fiancé took my son as his own sInce the age of two. My sons father stop comibg around after he had his second child and completely disappered after he found out I was in a relationship withmy fiancé. He hasn't paid child support in two years and is bearly $18,000 in arrears. Oh and the last time my son was with his father mysteriously contracted oral hsv I and his dad xould not explain how it happened also lied about takibg to seek medical attention my son lost ten pounds because he could not eat and had regressed mentally (wetting the bed, having bad dreams, scared all the time).
