Divorce Advice for Men | Fathers Rights Divorce | Child Custody

I was wondering if there was a statute of limitations on adultery. My wife had an affair about 3 years ago. I was wondering if I can still divorce her under the grounds of adultery after the time lapse.

My ex filed for full custody of our children after her re-marriage. The last "visit" to court was over a year ago with no new motions having been filed. Is there a time limit on her original motion? Or will the motion stay open indefinitely ?

I recently found out about a son that is the product of a one night stand. The mother called me once 12 yrs ago to tell me she was pregnant, I offered to pay for a paternity test, and she hung up on me, moved away, and came back after the child was born. I offered once again for a test, she declined, so I dismissed the idea. I saw the mother on many occasions afterwards, in town, same social events, whatever, and the child was never mentioned. Now, 12 yrs later, she calls and wants me to see him. This time she agrees to the test, which I paid for, which confirmed he was mine. I added the boy to my insurance, and commenced to seeing him and spending time and money, which she stated she didnt want, on him. Now, 9 months later, she not only wants child support, but 12 years of arrearages for years I could have been developing a relationship with him. I now have a family, and survive on all of my income. I don't know how I will afford to raise my current family and pay child support. The mother makes as much as I do a year. My question is, am I responsible for back support when she failed to inform me? Will I have to go by the guidelines although it will put my family in a terrible bind even though she is doing as well as I am?
