My friend hid her child’s father for 4 years—should I cut ties?

They broker up for irreconciliable differences. A month later, she find out she's pregnant and ever since kept the same story that it was a ONS mistake and she doesn't know the dude.

Her daughter is now 4 years old. Somehow her ex boyfriend contacted me, asking how to reach her because the girl looks like him and other calculations he did regarding her pregnancy.

Fast-forward I helped him get a paternity test and it was positive. Upon confronting my friend about it, she finally admitted the ONS story was false. She always her ex boyfriend was the father but just didn't feel like telling her and decided to raise her daughter on her own. I'm very pissed.

The guy wants to file a lawsuit against her for never even informing him. He wants to be with his daughter and my "friend" boots him. What can be done?
