He left the state to be with another woman while our daughter fights for her life in the NICU can I get him for abandonment and he'll lose all his rights? He has no intentions on coming back.

No. It doesn't work that way.

Did you read this?

Since your child is in a hospital then there is no abandonment. Im sure the doctors and nurses around her are doing all they can. I hope she gets better soon and recovers quickly.
