So my wife has been cheating on me and she decided that she wants to be with the man she is cheating with. She is pregnant and she got pregnant while we were married, but it might not be my child. So I guess I have a few questions to be answered, #1 Can I not sign the divorce papers until she gets a DNA test in the 8-13 week area of the pregnancy? #2 If it's not mine do I have to pay child support?
