If you met someone online and then got together with them and they had told you when you started talking that they weren't speaking to anyone other than you but then after a few months found out that wasn't true but they told this other person before asking you out that they didn't see a relationship with them but then continued to message them and talk about meeting even though they had told you they had no intention of doing that. And they had told you this other girl is their cousin and had continued to say that throughout the relationship. Would you class that as cheating?
