Cheating: Are there levels? Or just the same?

So, is this a question we all ask ourselves or is it just me? Is Cheating just the same in every case or are there levels to it that make one worst case worse than the other?

Infidelity (synonyms include cheating, straying, adultery (when married), being unfaithful, or having an affair) is a violation of a couple's assumed or stated contract regarding emotional and/or sexual exclusivity. Other scholars define infidelity as a violation according to the subjective feeling that one's partner has violated a set of rules or relationship norms; this violation results in feelings of anger, jealousy, sexual jealousy, and rivalry. Other than the textbook definition of cheating, psychologists or moralists will say cheating includes emotional bonding with someone other than your partner or lustful feelings & thoughts towards the other person.

Without going much into context about why people cheat, the other day we came across an interesting article about a man confessing to a relationship with his mother in law in a  very unapologetic way and the first question that came to mind was; what is worse, the fact that he cheated or that he cheated with his mother in law?

Sometimes, couples have been able to heal & forgive a cheating partner for different reasons. Other’s won’t hear of it because the cheating felt too close to home, maybe with a friend, a sibling or in this case a relative.

" My wife's mother is old chronologically but young physically ", he said, adding that meeting her was the most beautiful thing in her life and he doesn't want to stop.

" If I could, I would get her pregnant and I would have a family with her" | "the man saying that they had both developed " | " a multi-dimensional love and relationship " | " that goes beyond his understanding "

That brings us to the question? Are there levels to cheating that make some cases more acceptable than the others or is it all just the same?
