What is the name of your state? illinois I've been divorced for about 15 years now. I got married because I thought I had gotten my then girlfriend pregnant. She made me believe it was mine, along with her family. That baby is now 22 years old and I found out a few days ago from the second child that "Shawn" isnt mine and that right after Shawn turned 18 he was introduced to his real dad. The second child told me he had entered his mother's house and she said "Mike , I'd like you to meet Shawn's real dad." I havent seen Shawn for nearly 15 years but still payed child support because I believed he was mine.We had 3 children all together before the divorce and at one time I payed $225.00 a week for child support. My question is , is there anyway I can get her to pay back money , because in my eyes she committed fraud. Mike has told me he would go to court over this because he said this wasn't right
