Is cheating only sexual interaction or can it also mean emotional cheating or just spending time alone with another person?

Is it different when men cheat or when women cheat?

Do you associate cheating with high value or low value behaviour? I believe that if you had lots of options you wouldn’t feel the need to cheat, you would just break up with them.

Is cheating more acceptable in a marriage or a relationship? Kinda referring to my last point, I think cheating in marriage is different to when you’re in a relationship. If it’s just boyfriend/girlfriend, then it is pretty much casual and you can break up easily and find someone new, and I think cheating is less acceptable here. I guess my biases make me believe cheating is more acceptable in marriage.

Thoughts?
