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 (https://www.askmehelpdesk.com/family-law/child-abandonment-read-first-364259.html)?

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.
