If you were cheated on, what would upset you the most about it? Would you be upset? Do you think that cheating is forgivable?

The dishonesty and breaking of trust would upset me most, because I don't trust easily. And yes, I'd be upset---I've never cheated on anyone---I've [b]left[/b] first. Whether or not I could forgive would depend on several variables, starting with the trust being reparable or not.
