Besides physical and emotional, what do you consider other types of infidelity.?

I didn't ask her to explain what she meant at the time, but my partner said nothing physical or emotional has every gone on with another guy, but that has done other types of infidelity. It was kind of in the middle of a conversation about other somewhat related things and kept going on so I never really had a chance to ask her to tell me more about that. I will when the time is right. I am wondering what you consider other types of infidelity.
