Yes, you could get an NC attorney and file a AofA lawsuit against her. If she lives in NC and the affair occurred in NC then she is open to a lawsuit from you. So is your husband from her husband. I would suggest you try to contact him and pool your resources. It will be expensive.
With these things you need to ask yourself a question. Why are you doing it? If for revenge against her or your husband then it is not worth it. If the laws protect you adequately then simply get alimony, get child support get half the assets and move on. She may not know your husband is married. If that is the case, despite what has been done she didn’t set out to destroy your marriage. I just don’t believe in using the AofA in that case. Believe me I know what I am talking about.
