6 years ago, I was married to a woman and we had a boy in the state of OK. I "assumed" he was mine, knowing that that things didn't add up but I wanted to believe. We divorced 3 years ago in the state of TX and I was ordered to pay $750 a month in child support (I am only an E-4 in the military). My gut has been telling me for quite some time that I did not think that he was mine biologically. I asked his mother again and she assured me I was. I still wasn't so convinced, especially when he doesn't resemble her or myself. So, I did a DNA test on the outside and found out that he is not biologically mine. I am very upset about this. I have a great relationship with him. My question is this, if this were to go to court, what would the judge say about the child support? Am I still going to be obligated to pay when it has been proven that he is not mine in the biological sense. After the DNA results, she confessed that she knew all along that he wasn't mine because of the dates and he looks just like this other man. The biological father is apparently here in the state of TX and has no idea that he exists because he evidentally had a family and my son was the result of a fling with her right before we had moved to OK. Would this be a case of paternity fraud? Does Texas acknowledge that or would that be the state that he was born in (OK) with the birth certificate? My son only knows me as his Dad. I do however feel that his biological father should have the right to know him and be a part of his life. What rights do I even have now and will I still be obligated to provide child support if his biological father is in the picture? Paternity fraud? I don't even know what my next step is. I think I am still in the stunned, is this really happening stage.

Thanks for any information.
