My boyfriend is calling me an associate?

Found out boyfriend is cheating with a old costumer. I run a business with my boyfriend and he has been in contact with a girl he met that purchased something from us. They have been sexting for years and planning dates. He has been telling her he’s single. She has screenshots of his dick and a little bit of his face. I found out he has been referring to me as an associate he works with. What should I do?
