Alienation of Affection: Criminal Conversation in North Carolina

My question involves a marriage in the state of: North Carolina. We still observe AoA and Criminal conversation. My wife and I have been having issue for maybe a year in and off. She has never actually moved out. Although she has an apartment now and has only stayed there twice in 2 months, me the other. She had a relationship with a guy and they had sex during this period. She is pregnant by the man so there is no denial because we have not been intimate. No separation papers have been filed or divorce. She has spoke of divorce. She met this guy while we appeared to have a viable marriage. Celebrated anniversary and family vacation. It is unknown who made the move on who. She met him while staying at my family beach cottage without me.

From what I know. He is a young guy who perhaps flunked out of college. His dad is a divorce lawyer and is well off as far as money. This guy lives in his dads apartment complex so I know of no dominates of him

Do I have a case? Would I just be wasting my money for divorce leverage? I would like to this guy to pay for his doings because he knew of me and I even payed him a very respectful visit.
