I have a male friend who was in a relationship with someone. She cheated on him and he broke the relationship up. She came back and said she is pregnant however the figures didn't add up for it to be my friends child. However the other guy doesn't know this and she is now going to terminate the other guys baby 13 weeks into pregnancy. He believes she is terminating my friends child and is planning a life with her. Does he have a right to know the truth?
