From Merriam-Webster:
: to practice fraud or trickery denied the accusation that he cheated b : to violate rules dishonestly cheat at cards cheating on a test 2 : to be sexually unfaithful —usually used with on was cheating on his wife
I think the real issue is each person’s definition of “unfaithful.”
But that’s your definition of unfaithful, not necessarily Kalani’s or Asuelo’s. I personally don’t think watching porn or strippers is cheating, but in a relationship where people view that as unfaithful, it would be. Some people don’t view messaging people outside the relationship in intimate ways as being unfaithful, some people do. My point is that there isn’t one specific thing that comprises unfaithful/cheating behavior.
