Facebook Romance Scammer

My previously faithful wife of 37 years was carrying on an emotional affair with a military romance scammer on Facebook for over five months.  I warned her repeatedly about the possible danger.  She paid no attention but kept talking to her so called friend. To be with her internet lover she sent him over 3000 dollars for him to meet her and carry out a physical affair,  I discovered the affair when my credit card company contacted me with a fraud alert. I ordered her to leave which she did and promptly ended the affair,  I subsequently discovered she had been catfished  by a woman in Ghana who is the one actually receiving the money.  She has apologized and said she was feeling bad about getting older and was not looking for a relationship outside our marriage but was love bombed by this person until she was so high on the things he was saying to her she thought she was madly in love and  would have done anything he asked short of divorcing me which he demanded twice and she refused. She says she never stopped loving me but was addicted to how he made her feel about herself.  I can't eat or sleep, we are trying to work through this.
