Better to lie, or to break trust?

[Sperlock]

I would tell the truth, and I would rather that my S.O. do the same. It would hurt me more to happen to find out later, some other way, that not only did she cheat, but she hid the truth from me. It would be more painful to me and make me wonder, "Has she cheated since then? Is there anything else that she has hid from me?"

While I am not denying that finding out the S.O. cheated would hurt, it would be easier to recover from it and heal the relationship than if the S.O. had also hidden the truth. To me, at least.

As an additional thought, it's also possible that hiding it may make cheating more tempting when a relationship has hit a rough spot...hey, I hid it once, I can do it again. Just once more and I will stop.
