“Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves.”

-Matthew 10:16, KJV

If a cheater did not come clean on their own, the chances of true repentance diminish greatly.

I would warn you to be prepared for either anger over discovery or a slew of false promises. They may even tear up to manipulate your pity in an effort to avoid taking responsibility.

Please be careful.

All cheaters are liars. They manipulate. One of their most powerful weapon is your commitment to the marriage. They clearly are NOT committed to the marriage as God intended.

Such cheaters may ask how you know:

I would NOT recommend disclosing everything as then you may never discover if they are just talking about remorse as opposed to actually living in repentance.

The important piece of information is NOT how you figured out that they were cheating. At least, it is an unimportant piece of information for a person truly remorseful and repentant for cheating.

For someone desiring to continue the cheating, how you figured out is a key piece of information for them in order to continue manipulating you and others.

A cheater looking for this information is signaling a strong commitment to continuing in sin. It speaks volumes about their character or actually, their lack of character. Beware!
